Hi PratikUddeshya-7348,
'Approval Status' and 'Approver Comments' come from the built-in feature 'Content approval', you can enable it in 'versioning setting'
And its comments stores in the field 'OData__ModerationComments' :
Check https://www.c-sharpcorner.com/blogs/getting-approval-status-and-comments-in-flow
And there is an approval workflow :
It will add a 'xxxworkflow status' column into the list. But note that this is a different feature.
And its comments store in taks item:
So you can retrevel it in the task list (the list that is assoicated with the workflow) , and you can filter the task item by WorkflowItemId/WorkflowListId (or other fields).
