Capture Approval Comments from SharePoint Approval

I am using a SharePoint list for items that are being independently worked. Once the work item is complete an approval is sent for review. The approval request is done on the list with the built-in function not using power automate.

How can I capture the approval decision, date and comments using the basic built-in function using power automate?

I don't need to send an email. 

I cannot have the flow triggered on an item once it is created as the created item will be worked at a later time. 

I just want to capture data related to the approval decision.
