Cant get 3d to work

I dont know what i need to do or what im doing wrong.

I am uploading the file format that it’s asking for. I also tried a zip file. No matter what, I cannot get the 3D model to show.

Then I download a third-party 3D model program, and I just upload this file format glb, and it shows perfectly. But I would like to have less plugins for these. So, anyone have this 3D going and how is your process?
