Removing the cover on the BrewPi Spark

This may sound like a silly question, but what is the trick for removing that black plastic cover?

There seem to be four small tabs holding it in place, two on the top and two on the bottom, but there doesn’t seem to be any play in them.

Should the tabs be pushed in, should the cover be pulled out, or … ?

Thank’s. I tried something like that, but was afraid to break it :slight_smile:
