Depends what you mean by live stream. The Camera on the A1 maxs out at 1 frame per second, but through Bambu Handy (their mobile app) you can monitor and control what happens on your printer from remote locations. One frame per second is not great but it's enough to give you an idea how your print job is running.
have you made this yet?
If you read the full thread you'll see that I linked the repo on GitHub earlier. I have not published it to the official plugin repo.
