Exporting .gltf to Powerpoint

Hello guys

Can’t figure out one issue with exporting.

I’m trying to transfer my 3D model from Blender to Power Point. When I export .gltf object, it’s exported only with basic colours. No textures, no shading and nodes effects are kept. The coloures which are made with nodes, are simply white after exporting. Have tried lots of things, but nothing works.

So how do I export an object to save all the settings like textures, opacity, emission, in order to import into Power point?

I think the answer may be somewhere here:
