cordova-plugin-background-mode VS cordova-plugin-local-notifications

I am trying to bring my Capacitor 3 + Angular app in to the foreground when receiving a data only push message. The aim is to present the user with a “Phone ringing” screen like a normal call. I have been able to code in the push messages and have them receive and process but this is all when the app is running. I have tried using cordova plugin - background mode but it causes Gradle compile errors. I’m not sure where to go next - surely this is a common function so am unsure why I am unable to find help on this.

Has anyone been able to keep a Capacitor 3 app running in the background on Android? I've tried using this powermanagement plugin, background mode plugin, etc. but app activity consistently stops after about 5 minutes of switching to another task.

Cordova Plugin Background-Mode

I've recently been working with the Local Notifications plugin https://ionicframework.com/docs/native/local-notifications and am trying to set up a progress bar in the notification to show progress of a set of files being uploaded to a server. I've set up a basic test to display the notification and update the progress bar but it is playing the notification sound on my device every time the progress bar is updated. I've tried a few options, even setting the sound property to null and none of them have seemed to work. I have to imagine that if there is a progress bar property that you should be able to update it without re-triggering the notification sound every time, but the documentation in the Github Readme doesn't show much.
