Where to put the sound files for push notifications

I’m trying to use a custom sound when receiving push notifications on iOS, but i can’t find where to actually put the sound file.

Is there anyone who can point me in the right direction here?

I can add that I am able to play the default notification sounds, so i know that receiving push actually works.

What service (Ionic Push? OpenSignal?) and plugin (Github, npm link) are you using in what way (Ionic Native?) to handle Push?

I’m using Azure services, and Ionic Native’s https://github.com/phonegap/phonegap-plugin-push for handling Push.

Ok, then have a look at the documentation of the plugin:
which also links to https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/SupportingNotificationsinYourApp.html#//apple_ref/doc/uid/TP40008194-CH4-SW10

This should help.
