	Provides a remote candidate to the ICE Agent.
STATUS	restartIce (PRtcPeerConnection pPeerConnection)
	Instructs the RtcPeerConnection that ICE should be restarted. Subsequent calls to createOffer will create descriptions to restart ICE.

NullableBool	canTrickleIceCandidates (PRtcPeerConnection pPeerConnection)
	The canTrickleIceCandidates attribute indicates whether the remote peer is able to accept trickled ICE candidates. The value is determined based on whether a remote description indicates support for trickle ICE. Prior to the completion of setRemoteDescription, this value is null.

	Initializes global state needed for all RtcPeerConnections. It must only be called once.
STATUS	cleanupWebRtcClientInstance ()
STATUS	deinitKvsWebRtc (VOID)

	Get peer connection related metrics.
STATUS	setOnTwccFeedbackReceived (PRtcPeerConnection pPeerConnection, UINT64 customData, RtcOnTwccFeedbackReceived onTwccFbReceived)
	Configure a custom TWCC feedback received callback. When TWCC feedback arrives from the remote peer, this callback is invoked to update the congestion state. If not set, the SDK uses a default EMA-smoothed least-squares trendline estimator.
STATUS	setOnPeerCongestionFeedbackFn (PRtcPeerConnection pPeerConnection, UINT64 customData, RtcOnPeerCongestionFeedback onPeerCongestionFeedback)
	Configure a callback invoked when the SDK has congestion context ready for the application. The application uses this to adjust encoder bitrate or other media parameters.
