title: Remove Granting explicit consent using the "Grant Permissions" button in azure AD
body: <p>when an app is registered in azure ad, to give permission to the app, we can grant consent to an application's delegated permissions on behalf of all the users in your tenant by clinking "Grant Permissions" button. How to undo this permission once it is given? Or, it can't be undo from azure portal once it is clicked? I am confused as it is always of same color and always ask "Do you want to grant...." dialog and "No" doesn't undo the action.
