showAndUploadToGitLab does not provide a means of setting extra

Is your feature request related to a problem? Please describe.
Looked through the various classes in the feedback lib src code.
Could find any way to set up the extra map while using the gitlab extension lib.
I am basically trying to set up info like the logged in user id in extra.

Describe the solution you'd like
Some means of setting extra either before or after showing the feedback screen.
