Workflow action button on PPM email notification URL

HI everyone,

I am working on a changes that involves sending an email notification after a request is saved.

The requirements of this email notification is that the recipient can click on the link provided in the mail and then select Approve / Reject.

May I know if it is possible or doable in PPM? or is there any workaround on this?

Appreciate you help on this. Thank you!
