request for using X55 with Carbon X1 Gen9 under debian bookworm

Wed Jun 15 12:48:34 UTC 2022

Hi Bjørn,
debian bookworm now has 5.18 as Kernel and modem manager detects the
snapdragon on wwan0mbim0 type gsm
Version T99W175 F0 1 0 0 9 DT 003 075

I pressed the button enable and nothing is going on.

# modem-manager-gui
