How to use the react-native-callkeep.endCall function in react-native-callkeep

handleTerminatedEvent = () => {
    const {
      setCallFinished,
      call: { additionalCalls, tempRemote, remote, onCall, uuid },
      removeAdditionalCall
    } = this.props;
    logMessage(`additionalCalls: ${additionalCalls}`);
    if (additionalCalls > 0) {
      removeAdditionalCall();
      this.addCallToRecentCalls(tempRemote);
      setCallFinished(true, remote);
    } else {
      this.addCallToRecentCalls(onCall ? remote : tempRemote);
      setCallFinished();
    }
    RNCallKeep.endCall(this.getCurrentCallId());
  };

const hangup = (callUUID) => {
    RNCallKeep.endCall(callUUID);
    removeCall(callUUID);
  };

endCall() {
        RNCallKeep.endCall(this.callKitUuid);
    }

hangUpCurrentCallAction = () => {
    const {
      call: { uuid }
    } = this.props;
    const { toneAPI } = this.state;
    toneOutMessage(`Hang up current call`);
    RNCallKeep.endCall(uuid);
    return toneAPI.hangUp();
  };
