function App() {
  async function handleSubmit(e) {
    try {
      if (channelRef.current.value === "") {
        return console.log("Please Enter Channel Name");
      }

      setJoined(true);

      rtc.client = AgoraRTC.createClient({ mode: "rtc", codec: "h264" });
      const uid = await rtc.client.join(
        options.appId,
        channelRef.current.value,
        options.token,
        null
      );

      // Create an audio track from the audio captured by a microphone
      rtc.localAudioTrack = await AgoraRTC.createMicrophoneAudioTrack();
      // Create a video track from the video captured by a camera
      rtc.localVideoTrack = await AgoraRTC.createCameraVideoTrack();

      rtc.localVideoTrack.play("local-stream");

      rtc.client.on("user-published", async (user, mediaType) => {

          // Get `RemoteVideoTrack` in the `user` object.
          const remoteVideoTrack = user.videoTrack;
          console.log(remoteVideoTrack);

          // Dynamically create a container in the form of a DIV element for playing the remote video track.
          const PlayerContainer = React.createElement("div", {
            id: user.uid,
            className: "stream",

          // Play the audio track. Do not need to pass any DOM element
          remoteAudioTrack.play();
        }
      });

      rtc.client.on("user-unpublished", (user) => {

        playerContainer.remove();
      });

      // Publish the local audio and video tracks to the channel
      await rtc.client.publish([rtc.localAudioTrack, rtc.localVideoTrack]);

      console.log("publish success!");
    } catch (error) {

    }
  }

      rtc.localAudioTrack.close();
      rtc.localVideoTrack.close();

      setJoined(false);
      localContainer.textContent = "";
