Hi All,
I want to ask, is the feature in Ms flow for approval process, can be custom directly from the SharePoint list?
scenario: I have a SharePoint list with field 'Action' with data type choice 'Approve' or 'Reject'

And field 'Assign To' with data type 'Person or group' from email grouping in SharePoint Group

Because I need, when Approver-1 to do approved on SharePoint List with choose 'Approve or Reject' and put email in Assign To field for next Approver, my flow according to such needs. But the actually conditions, Approver-1 not choose yet 'Approve' or 'Reject in Action field (I waiting to 5 minutes) but, my flow approved or rejected automatically with sending double email notification.
With this my issue, I'm used 'delay' trigger Ms Flow with duration 5 minutes, but when Approver-1 to do Approved and put email Assign To to Approver-2, Approver-2 must wait for this notification email for 5 minutes and Approver-2 receive double email notification.

How is the best practice for ms Flow that is created?
Whether approval process Ms Flow can be customization with collaboration on SharePoint list?
With a resource that is in Office 365 E3 without Plan Premium 1 in Ms Flow.
Please advice ya.. Thanks
