Any way to upload or edit a file in a Github repo through Unreal Engine?

To be clear, I don’t mean using source control.

I’m trying to build a login and registration system and I was able to use the VaRest plugin to call a .json file in a github repo and check if the file contained the data I needed to verify a login.

But I’m trying to find a way to register a user. Is there any way to edit this .json file through blueprint code and reupload it back or something fo the sort?

I tried using Google Firebase but it’s too complicated and I have negligible server code knowledge.

Halp appreciated.
