Can't connect to libvirt

Hi folks! I'm trying to connect to a self-compiled libvirt 9.10.0 from python, but get the following error: Python 3.12.0 (main, Oct  3 2023, 19:47:47) [GCC 11.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. libvirt: DBus Utils error : error from service: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.libvirt.unix.monitor is not registered Traceback (most recent call last):  File "<stdin>", line 1, in <module>  File "/home/user/sw/python3/lib/python3.12/site-packages/libvirt.py", line 349, in openReadOnly    raise libvirtError('virConnectOpenReadOnly() failed') libvirt.libvirtError: error from service: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.libvirt.unix.monitor is not registered What is the issue here?
