phpPGadmin installed through web apps doesn't work

phpPGadmin version 7.13 doesn’t support PHP 8.x

I see there is a better maintained version here:

Can this be the version installed through the web apps selection? The current version does not work.

Web App version looks pretty old
Released: November 7th, 2020

Yes. It is old.

Anyone know how this can be updated??
