Chrome extension no longer works

Unfortunately this chrome extension no longer works and now also throws the `Uncaught (in promise) ReferenceError: SharedArrayBuffer is not defined` error.

I've been trying to build a chrome extension using locally stored ffmpegwasm files and came across this example, but sadly it doesn't seem to be supported anymore. I've attempted to run the ffmpeg.min,js and the core in chrome's extension sandbox as well, but this didn't make any difference.

Would it be possible to create a new example extension demonstrating how to do this without encountering the SharedArrayBuffer problem?
