How to send consumers tag to header

Hi guys,
I implemented a system with Kong and Django in Docker, which is register in Django and authenticated in basic auth Kong.
I use this system for SSO and API management.
When Kong send APIs to other projects, other projects get usernames through header (X-Consumer-Username) and perform operations according to the usernames defined in all microservice projects.
Now I want to send the consumer tag where the username is stored to the projects with Kong header, what is the solution?

I’ve been struggling to find a solution for this as well. Have you found a solution for your problem?
