micropython-firebase-auth library not available in the latest micropython (1.20.0) version #2

The newly changed package manager mip can neither find any micropython-firebase related libraries, nor does the latest micropython have 'upip'.
This implies neither
import upip
upip.install('xyz-related-to-firebase')
nor
import mip
mip.install('xyz-related-to-firebase')
will work.

WORK-AROUND
Use an older version of micropython (I wish I got this idea sooner my problems would've been solved by now smh.)

WARNING
I don't know what libraries are available with the new mip package manager other than firebase-related libraries. I suggest checking them and mentioning the version of micropython compatible with them.
