How do I delete the "Tab Group Favorites" bookmarks group in Safari?

How do I delete the Safari "Tab Group Favorites" bookmark group? (I don't mean the "Favorites" folder). It shows up in my Bookmark sidebar. I don't even know how it got created. It contains folders I no longer want. And I can't rename anything within the group either. If I right-click the group or any of the folders within, I'm presented with a "Open in Tab Group" option. There's no delete option. I searched online for an answer and didn't find anything. Is there a way to edit the .plist and delete it that way?
