Enable fails for QUALCOMM modem with MM 1.20.4

[Martin]

Hi,

this used to work long time ago on Debian 10 or 11, but now on
Debian 12 (modemmanager 1.20.4-1, libqmi-glib5 1.32.2-1), I get:

$ sudo mmcli --modem=0 --messaging-list-sms
error: modem not enabled yet
$ sudo mmcli --modem=0 --enable
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.libqmi.Error.Protocol.MissingArgument: Couldn't register for power indications: QMI protocol error (17): 'MissingArgument''

Am I missing something?

$ sudo mmcli --modem=0
