If it doesn’t work out of the box, there’s this fix which I’ve used before which has gotten it to work on my M1 Mac: M1 Support Workaround - have you got that in your project too?
I’m currently on 2021.2.7f1 on the latest M1 Macbook Pro and have gotten it to work with that fix. I’m not sure if the fix itself is in the actual ARDK in that version… but it’s worth a try if you haven’t already 
Let me know how you go!
