The --debug goes in the ModemManager daemon call, not in the mmcli
client call. You need to run the whole ModemManager daemon process
with --debug.

If you're using a standard Linux distribution, you may need to modify
the systemd init script at /lib/systemd/system/ModemManager.service so
that the ExecStart line includes --debug, e.g.:
  ExecStart=/usr/sbin/ModemManager --debug
Once you've modified the init script, you'll need to reload and restart:
  sudo systemctl daemon-reload
  sudo systemctl restart ModemManager

If you're using a custom distribution, you may have a custom way to
start the ModemManager daemon.
