When working with published/shared branches with other people, the advice with git has always been that history is history and not to be changed after publishing, unless there is an emergency like a security incident.
Aside from that we need might need to clarify what the question is. With shared code & git, it’s nice to use a branch & merge workflow, and it’s nice to make incoming merges as clean / nice as you can do the resulting history is as smooth as it can be while capturing what happened at a reasonable granularity. These are today’s conventions though, and it’s really up to the team to decide how to balance shared work, and what people feel are the most important workflows and tools.
You fix your local tree before sharing it. Alternatively, you can communicate with your team and tell them they'll need to run git fetch && git rebase -i origin/main to drop your erroneously merged commits.
