Collaborators and Pull Request, what's the difference?

Question

git

I want to add a friend to the project, the question is, how will it be easier for us to work?
As I understand it, adding a member gives write permission, i.e. he can immediately push to the master, right? A pull request is a change request.
How are these methods different? (although the pull request is more or less clear)
In the case of adding a participant, the work occurs as with one participant, i.e. everyone clones a turnip and pushes to master or a separate dev branch, right?

Answer 1

A pull request can be made by anyone who forked your project.
A collaborator with sufficient rights can accept this request. More details in the git documentation.
