Hello

I'm finding it difficult to discern whether the FCM-provided "collapsible messages" feature is available for iOS. This feature ("Non-collapsible and collapsible messages"), which uses the collapse_key parameter in FCM, is described in the documentation, however there is no information about whether this feature works for both Android as well as iOS.

For this type of feature to work, the new APNS api (which would send a "apns-collapse-id" parameter in the request header) would need to be used, but I am finding conflicting information online (e.g. https://github.com/firebase/quickstart-ios/issues/68) which indicates that "apns-collapse-id" is not available in FCM.
