Imported a new project: where is GitHub's api token stored in the gui?

I use gitlab-ce and I have imported a new project from GitHub. I typed in a GitHub’s api token, so GitLab could show me all my remote repositories.
The question is: where is that token stored in the GitLab config gui ? I have searched everywhere without success.

Thank you for any advice.

Hey there.

I believe the permissions is given by Github for an app and not for a token.

You could see which apps you provided access here and Gitlab should be there:

Thanks for the explanation
