I get the same results when using the IT Agent (Preview) and when I use the LS Agent (on prem) they are detected as Linux devices.
It doesn't appear that any investment is being made to have this great Windows solution properly support modern Apple devices, since documentation still refers to OS X and I cannot find anything that says Apple silicon.
