Convert OBJ + MTL to GLTF


I bought some assets from Turbosquid and converted them from OBJ to GLTF using an online converter.

The files I got are a .obj file a .mtl file and 4 images Diffuse, Glossiness, Normal, Specular and BumpScreenshot 2021-09-23 at 15.53.53

I can only convert the .obj file to .gltf, but how do I handle the material definition?

Can someone advice?
