That's a pretty funny/clever hack (took me a minute to figure out you're Zooming with yourself). You can also try AirServer (similar to Reflector). There's a free trial. https://www.airserver.com

I use it mainly for audio streaming from my phone to my MacMini / Stereo, and sometimes to play Alto's Adventure on a projector.

Or, if your Mac is compatible, just try Sidecar. There's a hack to make it work on older Macs, but I think officially it's tied to the ones that have hardware HEVC/h.265 support. http://osxdaily.com/2019/10/11/sidecar-compatible-mac-ipad-l...
