We display the play icon to run a playground only for .mongodb files. But we also have a possibility to trigger playground running events by using a command palette or shortcuts. In this case, a user can try to run a non-mongodb file or even start running a playground when no playgrounds open. It will try to run the last open playground. We should display playground running commands in the command palette only when mongodb file is open and show the running error for other file extensions or when the playground not found.
