How do I make the VST/Media Bay go away on the right?

Hi - The right quarter of my project window is taken up by a VST Instruments/Media Bay panel. Can someone tell me how to close that please and make it so it doesn’t come back?

8.5.20

Thanks much -

In the windows Layout Setup

Thanks, svenilenni!

Edit: I’ve clicked and right-clicked, looked at Preferences, File, Project, Window, Workspaces … can’t find that control.

Can you (or anyone) please show me which one?

Thanks!

In the upper left of the Project Window it’s the button that has several small squares on it.

Thank you, raino!
