Does docker container app go to sleep when hosted on Azure Web App Free Tier?

I know when deploying a regular app to an App Service it will go to sleep when idle and there is an option for Basic+ tiers to keep the app on.

I couldn’t find this option for a containerised app service on free tier and my app doesn’t seem to go to sleep.

Wanted to find out if anyone knows if the docker container goes to sleep when hosted on the Azure Web App service free tier?
