Thanks @markd for your response,
My use case is that I need to fetch the email Id of the user who created the access token, once I recieve that token in Mulesoft API. So I thought of including the email Id at the time of token creation which I can decode in Mulesoft. What is your suggestion to do this?
To get more details about this you can refer to this post that I created earlier:-
