Description

Scenario:
In 3 way call, when one call is on hold and another call is active. How to merge both calls?
Unable to find relevant APIs in RNCallKeep.

In Native iOS:
//Inform CallKit to merge calls
let groupCallAction = CXSetGroupCallAction(call: heldCallUUID, callUUIDToGroupWith: activeCallUUID)
let transaction = CXTransaction(action: groupCallAction)
CXCallController().request(transaction)

//Callback
func provider(_ provider: CXProvider, perform action: CXSetGroupCallAction) {
//Do changes to proceed further
}

Thanks in advance.

Research direction

Start by checking RNCallKeep's available call-grouping APIs and comparing them with the shown iOS CXSetGroupCallAction flow. Done would be a confirmed supported approach or a clearly documented limitation and next step for merging a held and active call.
