Scan the QR code from the screen

We can use getDisplayMedia API to do this thing.

• https://vueuse.org/core/useDisplayMedia/#usedisplaymedia
• https://developer.mozilla.org/en-US/docs/Web/API/Screen_Capture_API/Using_Screen_Capture
• https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getDisplayMedia

In this way, we obtain data from video conferences and remote video terminals on the computer.

Considering the limitations of using qr-scanner now, we may need to write our own scanner wrapper.
