Crash when sending Proximity event

RCTCallableJSModules is not set. This is probably because you've explicitly synthesized the RCTCallableJSModules in RNInCallManager, even though it's inherited from RCTEventEmitter.

Reproduction code

InCallManager.start({ media: "audio", auto: true, ringback: "_DTMF" })
InCallManager.setSpeakerphoneOn(speaker.current);

DeviceEventEmitter.addListener("Proximity", function (data) {
	// --- do something with events
});


NativeModules.InCallManager?.addListener?.("Proximity");

Version
react-native-incall-manager: 4.0.0
react-native: 0.70.4
iOS: 16.1.2

Start with the JavaScript reproduction using InCallManager.start, setSpeakerphoneOn, DeviceEventEmitter, and NativeModules.InCallManager.addListener("Proximity"). Trace the native Proximity event path and the RCTCallableJSModules error; done means the Proximity listener no longer crashes on the reported React Native and iOS versions.
