Hi Maru MMaru92 ,
Yes, an image would be good.
If you can post a Screenshot of your Shading Workspace, so we can see both your Shader Node Tree and your Viewport Rendered View of the Glass (Rendered, not Material Preview....make sure you are using Cycles), that would be great.
Here is an image of what I have done. Let me know if there is something that you need to see and the image is not showing. I don't think that the problem is the environment, the lighting or the HDRI, correct me if I'm wrong. Thank you so much for your help.
