UrBackup AlmaLinux9

Firstly thank you very much for such a great software, has been in production for years : )
Now we are migrating to AlmaLinux9 and have problem installing UrBackup client with Dattobd.
Can somebody check if this is actually the problem or is AlmaLinux9 not yet supported?

The installer outputs: dattobd not supported on this system

In script → https://github.com/uroni/urbackup_backend/blob/dev/install_client_linux.sh
there is only check for Centos8, not 9:
if grep "release 8" /etc/redhat-release > /dev/null 2>&1

If I temporary add “release 8” into /etc/redhat-release it recognize dattodb.

Is RHEL 9 (and Rocky, AlmaLinux9) supported at this time?

Thank you very much!
Greetings

RHEL 9 (AlmaLinux 9) was released May 2022, now we are 2 years later, and still no support?

Dattobd seems kind of unsupported in general at this point.
