Hi All,
           I have a schedulable class, I want ot call it from another class and make the second class invocable. how can i do this?
My class and invocable class is given below:-

global  class SendEmailToKnowledgeArticleFollower implements Schedulable {

    global void execute(SchedulableContext sc)
        {
            SendEmail();
        }
    public Static void SendEmail() {
        Set<Id> knowledgeArticleIdSet = new Set<Id>();
        Map<Id,Knowledge__kav> mapOfKnowledgeArticleVersion = new  Map<Id,Knowledge__kav>();
        List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMessage>();
        
        EmailTemplate et = [SELECT Id,Subject, Body FROM EmailTemplate WHERE DeveloperName = 'KnowledgeArticlePublished'];
        List<Knowledge__kav> knowledgeArticlesPublishedToday =  [SELECT Id,LastPublishedDate,PublishStatus,KnowledgeArticleId,IsLatestVersion,Title  
                                                                FROM Knowledge__kav 
                                                                WHERE LastPublishedDate  = TODAY ];
        
        if (!knowledgeArticlesPublishedToday.isEmpty()) {
            
            for (Knowledge__kav kav : knowledgeArticlesPublishedToday) {
                knowledgeArticleIdSet.add(kav.KnowledgeArticleId);
                mapOfKnowledgeArticleVersion.put(kav.KnowledgeArticleId,kav);
            }

            List<EntitySubscription> knowledgeArticleFolower = [SELECT  ID, ParentId, SubscriberId,Subscriber.Name,Subscriber.Email   
                                                                FROM EntitySubscription 
                                                                WHERE ParentId 
                                                                IN :knowledgeArticleIdSet];
            if (!knowledgeArticleFolower.isEmpty()) {
                OrgWideEmailAddress orgWideAddress = [SELECT Id, Address, DisplayName 
                                                              FROM OrgWideEmailAddress 
                                                              WHERE Address='techsupport_test@on24.com' 
                                                              LIMIT 1 ];
                        
                        
                for (EntitySubscription follower : knowledgeArticleFolower) {
                    List<String> sendTo = new List<String>();
                    Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                    Messaging.SingleEmailMessage getEmailTempResponse = Messaging.renderStoredEmailTemplate(et.Id, follower.SubscriberId, mapOfKnowledgeArticleVersion.get(follower.ParentId).Id);
                    sendTo.add(follower.Subscriber.Email);
                    // Set email contents - you can use variables!
                    if ( orgWideAddress != null) {
                        mail.setOrgWideEmailAddressId( orgWideAddress.Id );
                        // mail.setSenderDisplayName(orgWideAddress.DisplayName);
                    }
                    mail.setToAddresses(sendTo);
                    mail.setSubject(getEmailTempResponse.getSubject());
                    mail.setHTMLBody(getEmailTempResponse.getHtmlBody());
                    mails.add(mail);
                }
                Messaging.sendEmail(mails);
            }
    }
    }
}

Invocable class is given below:- 
public class InvocableSendEmailToFollowers {
    @InvocableMethod
    public static void SendEmailToFollower( List<Id> articleIds ) {
     List<Knowledge__kav> knowledgeArticlesPublishedToday =  [SELECT Id,LastPublishedDate,PublishStatus,KnowledgeArticleId,IsLatestVersion,Title  
                                                                FROM Knowledge__kav 
                                                                WHERE LastPublishedDate  = TODAY AND Id IN: articleIds ];
        SendEmailToKnowledgeArticleFollower.SendEmail();
    }
        
}
here i want that when i will call a flow from button after clicking of button flow will call the invocable and do the rest thing.
Can anyone help me with this?
