@LearnerSN 

what's your actual question?

[LearnerSN]

@Ankur Bawiskar : Requirement is to land on SP portal page when user clicks on M365 button.

[Ankur Bawiskar]

@LearnerSN 

can you please tell where this button is coming from and on which form?

[LearnerSN]

We configured this popup using a Client Script that calls spModal.open() and defines two buttons. Each button has its own action: function, and for the “M365 Meets My Requirements” button we simply added a redirect to the Service Portal.
