How to make a plugin for Discord (like vencord and betterDiscord) [closed]

Me and my developer are having a tricky time figuring out how we can make an add-on to Discord We’re solely making a simple Discord plugin that could benefit user experience. It is not a client, or discord modification app similar to Vencord and BetterDiscord. It is just going to add a few little buttons to the actual Discord app (on macos and windows)

We know it’s something to do with electron and js injecting but we really need a bit of a lift off as we dont know where to start when it comes to coding and actually testing our plugin on the Discord application.

How do we actually run and test our app, and make it work?

We’ve tried a few things, we’ve looked through the source code of betterDiscord and dmed developers but no one can help us.

We really just want to make a simple plugin to benefit user experience on discord.
