How to delete a specific desktop

TotalSpaces is saving a desktop as “Safari Desktop” for when Safari is full-screen. How do I delete this desktop?

When you use the green button to fullscreen an app, MacOS actually puts the app in a new space. The system does this automatically, so TotalSpaces reflects that in the overview grid.

If you return the app to normal size, the additional desktop will disappear - that’s the only way to delete it.
