Anyone facing trouble with Module Service Cloud Macros - Create and Run Macros?

I can't see Email Action on page layout. I got the same error of this link: https://help.salesforce.com/articleView?id=Why-do-I-receive-an-error-running-the-Macro-saying-that-the-action-is-not-available&type=1&language=en_US

I found users claiming about similar question that seems to be the same issue on this link: https://success.salesforce.com/ideaView?id=08730000000l1tPAAQ&sort=2
 

I'm just learning the basics of Apex, and I could use a little help writing a test class for a basic trigger I have that prevents users from deleting tasks. I've been at this for over a week now, and I've just hit a wall with it.

Could anyone help me out with a test class for this? I'll be sure to make it best answer :)

Thanks in advance.

trigger NoDeleteOnTask on Task (before delete)
{
   
    if(trigger.isDelete){
        Set<Id> allowedProfileIds = new Set<Id>();
        for(Profile p :[SELECT Id FROM Profile WHERE (Name = 'System Administrator' )]){
            allowedProfileIds.add(p.Id);
        }

        for (Task a : Trigger.old){
            if(!allowedProfileIds.contains(UserInfo.getProfileId())){
                a.addError('Task\'s can\'t be deleted. Please contact the system administrator if you require further assistance.');
            }
        }
    }
}
