Is your feature request related to a problem? Please describe.
I am trying to create a filter pipeline that will append metadata to the body in the inlet method using information from the user object. However, I would like to use the email address of the user since downstream services uses the email address to identify the user.

Describe the solution you'd like
Adding the user email to the user object here.

Describe alternatives you've considered
Workarounds I have considered:

• Querying the database by the user id
• GET /api/v1/auths/

Additional context
Downstream services: litellm, langfuse.
