Bookmarks sidebar now missing from Start Page in Safari 15.0?

In Safari 15.0, is there a way to show the bookmarks sidebar in the Start Page? My workflow used to be: open a new tab to Start Page > I see my expanded bookmarks sidebar just the way I left it > I click on a bookmark and go. The sidebar is now gone from Start Page and I see no option to put it back.

I now have to click into the favorites like folders every time in order to get to my bookmarks, or expand the bookmarks sidebar, click on bookmarks, click my bookmark, then close the bookmarks sidebar manually. Too many clicks. Even hitting Ctrl + Cmd + 1, clicking a bookmark, then hitting Ctrl + Cmd + 1 again to close the sidebar is two more actions than it used to be.
