Making a glass ball like a marble without HDRP?

I want something that will work in WebGL or Android, so HDRP is out. I can make a clear glass ball, but it has no depth. I need the Refraction piece, but without HDRP. Would prefer not to buy an asset. I trid using the code in the Glass Shader example, but couldn’t get it to work.

Any suggestions?

try this shader…
also could try 2 layers (2 meshes)… combine refraction layer, with a legacy shader , reflective->transparent with a cubemap environtment map
