Edit the MR directly to make changes. ## Implementation guide From [comment below](https://gitlab.com/gitlab-org/gitlab/-/issues/491514#note_2153507271): > In that vein, should you want to submit a PR, you can take a look at https://gitlab.com/gitlab-org/gitlab/-/merge_requests/143609+, which upgraded the support. Just at that level it's pretty simple, though maybe there is some additional testing we would want to do with a version major version jump. But in general, there shouldn't be much that needs to be changed in the code. :fingers_crossed:
