Cloudflare Tunnel TOS for intermittent video streaming

I’m using a Cloudflare tunnel to connect to Home Assistant.
I have a webcam viewing a 3D printer and on the occasions that I have a print running, I’d like to be able to intermittently check the webcam stream to ensure that the printer is still running correctly.

I understand that video streaming could breach the free Cloudflare Tunnel terms of service, however, I’d like to find out if video streaming to a small extent would be acceptable?
