### Current Behavior

If I have spotify playing music, then I launch my Capacitor app on iOS, the audio of the background app (music from spotify) is lowered. The system volume level seems to be unchanged, but the audio is noticably lower.

### Expected Behavior

The audio volume output should be unchanged when I launch the Capacitor app.

### Additional Information

- I'm using @vimeo/player to embed vimeo videos thoughout the app, but I noticed that when I uninstalled this package, the issue was still there.
- I have this seen this audio lowering called "audio ducking" in some places.
