Setting up WWAN 4G-LTE modem on existing install

Hello again!

I need some help setting up a basic WWAN modem on my ThinkPad T480s, it's a Fibocom L850-GL PCI modem, using a Golan Telecom in Israel SIM card with an active plan.

trying to follow the guide sent me to a barrier, as even after unblocking it with rfkill, ModemManager still wouldn't locate the modem.

outputs of rfkill and mmcli -L for reference:

[andaro@smolwrld ~]$ rfkill
ID TYPE      DEVICE                   SOFT      HARD
 0 bluetooth tpacpi_bluetooth_sw unblocked unblocked
 1 wwan      tpacpi_wwan_sw      unblocked unblocked
 2 bluetooth hci0                unblocked unblocked
 3 wlan      phy0                unblocked unblocked
[andaro@smolwrld ~]$ mmcli -L
No modems were found

also, output of lscpi -nn.
