My admin who setup sonarcloud, he left the company without re-assinging other to be new Admin. How to solve this

We use Github for authentication and We removed this email and also remove him out of Github organization. Please suggest. How to assign new guy to be new “admin”

Did you ever get a response - or were you able to find a way around this?

If you add back the same email, you could ask the SonarCloud Team to use that to verify your identity, and authorize adding another user of your choice as admin. Then you could use the newly admin to clean up.
