3D type and Materials Expand Appearance not outlining artwork

[ricks43263218]

Creating a type 3D logo in Illustrator 2022. Created - Window 3D and Materials, I needed to have the type 3D build extruded part to be a solid build without the light shading. When I went to Object - Expand Appreance it no longer creates outlines where you can select and change colors or in this case change the extruded part to a solid color. 

My question to get the Expand Appreance to work do you need to creat the artwork in Effect - 3D (Classis) in order for the Expand Appearance to work. 

Redoing the artwork this route the Expand Appearance works.

Correct. The Classic 3D option is the way to go for your purpose.
