Installing python nicegui on latest Linux (PI OS and (K)Ubuntu)

Can't be this hard, but I can't seem to find an easy way of getting the package nicegui installed for Python. As some of you are aware, pip3 no longer works for PI OS 64 Bookworm and for Ubuntu 23.10. Seems we are being forced to use apt install python3-<package> . Only there isn't one for this package. I don't use or want to use docker.. just plain o' Linux. The pip process was always so nice and easy to use which also picked up all the dependencies needed.

Any ideas?
