A belated report: I managed to install Sharaf’s build shared by hellozee on my ARM64 ChromeOS tablet and ran it just fine! Nothing crashed or errored out during my testing. 
The only issue I noticed was that stylus tilt does not work (which other Android painting apps on the tablet can work with), but pressure does. I’m not sure if tilt is supposed to work on this build on not.
And, of course, that the app is pretty sluggish, but part of that is because my tablet (Asus CT100P) is a bit on the weaker side.
