CATT and Google Nest Hub - Timeout issues

I just discovered CATT and it's really cool. With it I can cast any dashboard to any Google Nest Hub. The only downside appears to be that after about 10 minutes the hub shuts down the cast and returns to the boring old clock that it usually displays. Having a Hubitat Dashboard displaying 24/7 would be much more useful. Does anyone have any idea how I could keep the display from reverting after 10 minutes? I've tried a timed task and it sort of works but it re-casts every 10 minutes. This is accompanied by a sound and a reload of the dashboard with a several second delay. It's also really annoying if you happen to be in the middle of interacting with the dashboard when it happens.
