Error: "Command "compose up" not available in current context (default)"

Docker Desktop (Mac) version 2.4.00
macOS Mojave

I’m trying to learn Docker so I can use bazarr for downloading subtitles. I downloaded Docker Desktop and did the tutorial.

I then created a docker-compose.yml for bazarr. But when I try to run the docker-compose file so it’ll download and install the bazarr container, I get the following message in Terminal: “Command “compose up” not available in current context (default)”

I have no idea what this means or how to fix it. There really isn’t much on Google about this problem. And I don’t understand why the compose up would be in a different context.

Any suggestions on what’s going on and how to fix this?
