How to allow Plasmic components in slots?

Hey again! Is there a reference to allow Plasmic components in slots? I’m not seeing any of these work, referring to Vertical Stack or Grid.

allowedComponents: [
        'Vertical Stack',
        'Vertical stack',
        'VerticalStack',
        'Verticalstack',
        'vertical stack',
        'Grid',
        'grid',
        'PDPProductTitle',
        'PDPCompareAtPrice',
        'PDPSidebarHeader',
        'PDPVariantSelection',
        'PDPAddToCartRegion',
        'PDPExtraContentRegion',
      ],

only my code components seem to work when I use Studio

Looking to see these show up here

Maybe I just shouldn’t restrict at all…
