alexemanuelol/rustplusplus-credential-application — reverse-engineered prompt

Build me a small desktop app for getting the credentials needed by the rustplusplus NodeJS Discord bot.

I want it to feel simple for someone who is not technical. When I open it, I should be able to enter the Firebase API key, app id, and project id, connect to Firebase, and then see the credential values the bot needs in a clear way. Make it easy to copy the values, and show friendly messages if the Firebase setup is missing or wrong.

Please make it work as a desktop app for Mac, Windows, and Linux. Use the existing style assets if there are any, including the rustplusplus image and Discord invite image. Keep the interface clean and centered, with clear labels and no confusing developer wording.

Also add the basic setup notes so I can run it locally with npm install and the Electron dev command, then build release versions when it is ready.
