Hi, I was wondering if its possible to use "mutable-content": 1 in a VOIP-Notification in order to modify the payload, for example to download the caller-name from the server. Some sources mentioned that you can use the same keys as in normal notificationsm, which would include the "mutable-content"-key. A follow-up question would then be, are voip-notifications with "mutable-content": 1 handled by a Notification service Extension or are they immediately handled by CallKit. Thank you,
