How to properly rollback or remove the latest commit in github?

Question

git

Hello, I'm just learning git and I have a question, I'm making a project in Visual Studio Asp.Net MVC and when pushing to github, in addition to the files that I changed in my project, minor changes were pushed, those that are not of interest to view the commit history, t .e. all sorts of system files, etc. because of this, when you look at the commit page on the github, it lags everything, since there are a lot of files. Since I made a mistake, I didn’t add the .gitignore folder at first and didn’t put the files that need to be ignored there, now I need to somehow delete or change the last commit so that I first add .gitignore (as I understand it, there will be a separate commit for this ) and then again I pushed my main files, but without those system files, can you help me which set of commands should be used in this situation? Thank you!
