Git commit/push: Post process copy a file of repository to network share

I’ve got a file in my git repository which I’d like to provide for non-git users on a network share. Is there a possibility to automate this copying after a commit or push to gitlab?
It would be a kind of post process, the only feature which comes in my mind is CI/CD but I think it’s a bit overkilled only starting to copy one file. And installing / integrating CI/CD seems to be a lot of work.
Isn’t there something easier to post process this file copy?
A direct link on network share to gitlab repository needs to log in for an user and isn’t as easy as only double-click on a file.
Any clever ideas?

Thanks a lot!
