GPS/location services don't work with Maps after Bookworm upgrade

[biketool]

before I try the fixes I want to see if my problem is normal, seems like permissions but not sure where to whitelist the modem/GPS.

Code:

mobian@mobian:~$ mmcli -m 0 --location-enable-gps-raw --location-enable-gps-nmea
error: couldn't setup location gathering: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unauthorized: PolicyKit authorization failed: not authorized for 'org.freedesktop.ModemManager1.Device.Control''

this is a clean bookworm install with /etc/apt/sources set to unstable.


(edit)
I appended 'org.freedesktop.ModemManager1.Device.Control' with a ; as a separator to the whitelist of desktop IDs in /etc/geoclue/geoclue.conf 
I see I can get a short and correct GPS fix on gnome maps now.


(edit 2)
yet when I

Code:

mobian@mobian:~$ watch -n 5 mmcli -m any --location-get

I get:

Code:

error: couldn't get location from the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unauthorized: PolicyKit authorization failed: not authorized for 'org.freedesktop.ModemManager1.Location''

so in gnome maps there was a moment where I had location within a few meters, then a telephone network general location within a few km, finally only a fix based upon my regional IP address; what is going on?

I will take a break and see if there are ideas; this is permissions I think, but where else can I fix them?

I feel like we either need to build-in the geolocation to the Mobian builds, maybe with a true/false enable toggle in a conf file or we need a Bookworm specific tested solution instructions in the wiki to get us everyday-drivers a working GPS solution. Right now there is too much incompatible mix of versions in most wiki how-to guides.
