Hi,
I am trying to create a component which will update  any account feild by fetching record details and update it using update button. But how will I acess record using recordID and display it as outputfeild.
and How will I set those values back.
It will really help if anyone can guide me with this.
Here is my code according to my knowledge:

Component.cmp
<aura:component implements="flexipage:availableForRecordHome, force:hasRecordId">
        <aura:attribute name="recordId" type="Id" />
    <aura:attribute type="List" name="accountList"/>
    <aura:attribute name="name" type="string" />
    <aura:attribute name="type" type="string" />
     <aura:attribute name="phone" type="string" />
     <aura:attribute name="website" type="string" />
    
     <lightning:recordViewForm recordId="{!v.recordId}" objectApiName="Account">
         <lightning:card title="Update Account">
        <aura:set attribute="actions">
            <lightning:button variant="brand" label="Update Account" title="Update Account" onclick="{!c.updateAccountController}" />
        </aura:set>
