Update packed Electron app contents in closed network



I came across electron-builder and of course electron’s autoUpdate module.

My use case is to deploy multiple different apps in a closed local network.
The only thing I currently have at hand is a central git-server. My Idea was to install the same packaged electron app on multiple devices with the option to choose which app contents to load, e.g App1, App2 etc.

Would it be possible to just point each electron app to a different git repo on the central server via the option to choose, mentioned above and simply perform a git pull every time the app starts up to fetch the right app contents and it’s updates?

Is this the right path or am I getting something horribly wrong? Thanks in advance for the advise.
