How to restore default sidebar for PC?

I must have moved the OG sidebar by accident and then deleted something. Anyhow this is the closest I can get - by selecting Main for Sidebar, but I’m missing commands like Revolve/Rail Revolve, Sweep1, Sweep2 and probably other options. If I select another sidebar, then it turns into three vertical columns. Any ideas?

Run _ToolbarReset, but be careful, as this will wipe any customizations you have made to the default toolbar(s). If that’s the case, save it under a new name so that you can bring custom changes back into the new (reset) toolbar.

Thank you! Now when I click the Tabs at the top, their respective sidebar menus also load. Much appreciated!!
