How do I delete a custom workspace?

I have made a modification to a custom workspace and named it something else so now I have 2 workspaces that are very similar. I want to delete the older one. How do I do this please. I can not find anything on this topic oddly enough.

UPDATE: well. I found my answer right in the menu, "Open workspace Folder in Finder". I can delete it there.

Many thanks,

Houston
