How to record google meeting using selenium python

Question

I want to record a Google meeting using selenium python and upload it to the server.

After some googling, I understand that I need to create a bot, that will join the meeting. After joining the meeting, it will record the meeting (both audio and video) and upload it to the server.

So far, I created a bot that can join the meeting, but I'm unable to record the meeting. I tried sharing the browser tab. After the bot joins the meeting, it opens the tab-sharing option, but it is unable to share the tab.

var blob, mediaRecorder = null;

    let video = await navigator.mediaDevices.getDisplayMedia({video: {mediaSource: "screen"}, audio: true});
    let audio = await navigator.mediaDevices.getUserMedia({audio: true, video: false }) 

    // Assign the recorded mediastream to the src object  
    // video.srcObject = e; 

    // Combine both video/audio stream with MediaStream object 
    let combine = new MediaStream([...video.getTracks(), ...audio.getTracks()]) 

    mediaRecorder = new MediaRecorder(combine, {mimeType: "video/webm"});
    mediaRecorder.ondataavailable = (e) => {
        if(e.data.size > 0){
            chunks.push(e.data);
        }
    };
    mediaRecorder.onstop = () => {
        var filename = window.prompt("File name", "video"); // Ask the file name
        blob = new Blob(chunks, {type: "video/webm"});
        chunks = []; // Resetting the data chunks

Can anyone tell me how my bot will record the meeting? Any kind of help will be appreciated.
