What NM version? 'trace' is pretty old (since 1.0 from December 2014) so unless you're using a really, really old version of Debian I'd expect you'd have it. Anyway, debug would do.

nmcli gen help

This should be OK.

It routes it to whatever the syslog 'daemon' facility logs to (however that's configured on your system). Usually /var/log/messages or /var/log/daemon.log or sometimes your distro configures it to /var/log/NetworkManager.log.
Or if you're using a systemd-based distro, it would probably be in the systemd journal so "journalctl -b -u NetworkManager"

Does your distro use pm-utils, upower, or systemd for suspend/resume handling?
