Microsoft Blend 2017 how to import .obj image file

Trying to import an .obj image file into Microsoft Blend 2017 so that it can be used in Viewport3D. I can successfully import the .obj into the project, but cannot use it in the Viewport3D in the window.

Some links I found say to look for the "Insert" menu item after RH clicked on the .obj, but that menu item was not found anywhere. Any ideas on how to actually use the .obj image in the project would be helpful.
