Alright. However, I do not have commit access to push onto main. How do I proceed?

Someone who has commit access can push it on your behalf and you will maintain authorship for the contribution. I recently received commit access and have not yet pushed a commit for someone else, so I don't know exactly how to do it, but I can look it up in the documentation and try to push this for you.
