Remove videos on a Google Meet.js

// Open the Developer Tools, switch to the "Console" tab, copy and paste the following code:

(function () {
  for (const element of document.querySelectorAll('div[data-allocation-index]')) {
    // Remove all video panes, except the main one.
    if (element.attributes.getNamedItem('data-allocation-index').value !== '0') element.remove();
  }
})();

// Now, only the main presentation pane must be appearing. To make this pane cover the whole screen
// (from top to bottom), resize (expand or shrink) the Developer Tools, or simply close it.
//
// If the videos come back for some reason, run the code again.
