Smartsheet Application scope - Oauth authentication issue


I am trying to access smartsheet using OAuth authentication. When I trigger the bot with OAuth creds, bot is landing in a consent window where bot needs to click on Allow or Deny button

But bot is not getting the control back from smartsheet application scope to click on the buttons

I tried parallel activity with a click action, but it is not working either

This could be a bug, how to get out of this issue? Please suggest some solution

Thank you
