I have a branch `feature/my-changes` which I have made changes to. I pushed these changes, created a pull request, and have gotten feedback on my changes through a code review. My question is: Now that I see the changes I need to make in github (from code review comments), do I simply go back to my code editor and make those changes in my branch, make a new commit, and push again? Or should I be "checking out" a revision of my branch's history and make edits there? I'm not really sure how to proceed after this code review...
