I migrated my Cordova project to capacitor 6.0.0 (without a framework). My app uses jQuery Mobile, and the code is maintained in Android Studio. I managed to get all plugins to work except the cordova-plugin-fcm which is incompatible with capacitor. Instead I want to use the @capacitor-firebase/messaging, but I am unable to find any documentations/demos on how to include it in my project in Javascript.

The only documentation that I find is for capacitor with some type of framework.
