Citrix and Microsoft Edge

I build a Figma Website for my Company and they use Microsoft Edge Broswser, Chrome and Firefox in Citrix. The Website loads and works in Firefox and Chrome Citrix. It also loads in Browsers outside citrix. But if i open it in Edge Citrix it shows nothing, loads only 2 menü points in the top and thats it. Is there any thing i can do ore a place i can get help? I know this may not be an easy fix but i dont even know where to start looking for the problem.
