How to get the Confluence logged-in user’s email in a macro

[Arikrishnan]

We are testing a Prolaborate macro and need to retrieve the currently logged-in user’s email.
However, without additional permissions, we are unable to fetch the email.

• When profile visibility permissions are enabled, it works.

• When users keep their email hidden, the macro cannot access it.

• Our macro should not ask users to grant extra permissions.

Is there any authentication-based method, built-in API, or alternative approach to get the logged-in user’s email in a Confluence macro without requiring profile visibility permissions?

Can anybody help me with this?
