Does RPiPlay support Ubuntu MATE 20.10 64-bit on Raspberry Pi 4?

I successfully installed it and i run the command

sudo rpiplay -n PiAir

then I got

raop_rtp_mirror starting mirroring

the name PiAir did show on my iPhone(iOS 15.0.2) and I can select it. But then nothing happens, just the terminal. Should there be a window pop up?

I add -d and I got many
