How to deal with merging/grouping two calls?

[arunkavi]

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.
