Custom sound for notifications in IOS

[josuelmm]

Good day, how do I configure a custom sound for notifications on iOS. On Android it works fine, because from the backend I send the channel and sound, that is, setSound('sos'), setChannelId('sos')
and it plays the sound, but on Apple it always sounds something generic and I have not been able to customize it. On Android the file is called sos.mp3 and it plays.

Channel example, but this work only in Android
let dataChannel:any = { description: "", id: "default", name: "Default", importance: 4, lightColor: "#000000", lights: true, visibility:1, vibration: true, sound:sonido }; await FirebaseMessaging.createChannel(dataChannel).then((data:any) =>{}).catch((err) => {});
