Accessing CCTV Hikvision NVR

I have a Hikvision NVR that I need to access behind a Tmobile 5G Cell home internet.

the NVR is 192.168.0.5 on the local network.

The port is 8000. 

In the dashboard, I have created the domain

motomarine.loclx.io

But I am unable to figure out the command that I need in order to make it work. I assume that i need UDP to make it work.

loclx tunnel udp --reserved-domain motomarine.loclx.io --to 192.168.0.5

Incorrect Usage: flag provided but not defined: -reserved-domain
