There are two ways to use git:

- learn a basic workflow and ask/google for help for problems. A gui makes this slightly easier

- learn the underlying model for git. Then you probably still have to google for invocations occasionally but you would have to do the same with a sugary gui. And for complex actions in a gui the answer usually is 'use the cli'

Plus occasionally a gui does something incredibly weird like giving direct access to `git clean --force` like vs code did a while back.
