Modem Manager not detecting Qualcomm USB modem on Manjaro KDE

I use Manjaro KDE and I’ve been trying to use my qualcomm modem on it but the modem manager-gui is not detecting is.

Here is the result of lsusb:

Also here is the result of mmcli -L

I have tried some solutions I saw here and those ones on the Arch wiki.
Thanks in advance for your help.
