Documentation for the commands is in the reference manual:

https://www.acs.com.hk/download-manual/10212/REF-APG8201-B2-1.00.pdf

I guess someone needs to figure out the right commands and add them to
the code. That someone probably should probably be me, but likely not
any time soon.

Thanks! It does run, but it times out:
