A newcomer's question - how to submit changes?

[Liubov Chuprikova <chuprikovalv@gmail.com>]

Hello,

I wish to participate in the Outreachy program and I have chosen #890786 to start making contributions to the Debian Med project. I've fixed the bug locally and tested the changes following (hopefully) New Maintainer's Guide, and autopkgtest manpages.  

At this point, I would like to export these changes to the Debian Med repository to finally fix the bug. Unfortunately, I am not sure how to go about it. Should I request membership to the Debian Med group on Alioth page as Debian Med Group Policy says? Or a newcomer should follow a different procedure (e.g., post a patch on a bug tracker or find a sponsor)?

Thank you,

Liubov
