I'm build react native app and I'm looking to change notification sound to custom sound I have in format mp3. in appcenter docs I read that I need to add the new sound into Library/Sounds
sound: Add this key when you want the to play a sound. The value of this key is the name of a sound file in your app's main bundle or in the Library/Sounds folder of your app’s data container. If the sound file cannot be found, or if you specify default for the value, the system plays the default alert sound.
in xcode when I open my project I don't see any folder called Library or Library/sounds. and I'm not sure where to create it. I have Libraries folder and there is fonts inside it without any folder.

You can't use .mp3 file for ios, you can use .caf file
