Substance Painter plugin not working in Unreal Engine...

Hi,

I'm trying to use the Substance plugin in Unreal Engine, but it does not appear as an option in the Add/Import menu.  I have installed the plugin, and have activated in in the plugins menu in Unreal Engine.

I'm working with Unreal Engine 4.26, and I have both the older Substance Painter, as well as the Newer Adobe Substance 3d Painter.  I am on Mac OSX.

Any ideas?  Would love to get the plugin up and running!
