Recently we had a requirement to remove or hide the Approve and Reject buttons from the approval email as we wanted the user to manage it all from the Approval Center.
The way we implemented this is by replacing the Start and wait for an approval action with Create an approval, Send email notification and Wait for an approval action.
For Create an approval action, set Enable notifications as No this makes sure no email is sent.
Followed by– in the body, specify Send an email notification the Approval Center link.
Followed by Wait for an approval, specify the Approval ID there.
And the Condition control and the required logic.
After running the flow, the user will get the email and can click the link to navigate to the Approval center.
The user can then take the required action from within the Approval center.
The flow will wait for the user
