Can't found the entity in editor

I want to find out how to switch materials in glb in the project in this post, but I can’t find such an entity in the script

Hey, the graph node named “charactermedium” is within the model hierarchy. The easy way to check is to open the given glb model in the playcanvas model viewer and you will be able to see that there.
I have doubts about ‘characterMedium’ in the project,I want to know how to change the material of glb through this project. But I can’t find ‘characterMedium’ in this project

What does it mean?

When the GLB hierarchy is added to scene at runtime, there is a entity named ‘characterMedium’ when has the render component on it

okay,I found it,thank you!

I found it,thanks for your help
