I want use a Liquid Glass Icon in my project

I made an icon by Icon composer by Apple, and I want use it in my UE project, but I tried change icon in (project)/Intermedate/ProjectFiles/(Project)(iOS).xcodeproj and (project)/Intermedate/ProjectFilesIOS/(Project)(iOS).xcodeproj, They don’t work all, it also have default UE icon after these change.

When I want try to change the icon in Unreal Editor, I can’t change Project Settings > iOS > Required Icons in my Mac, but file .icon is a folder in Windows.

I use UE 5.7 and Xcode 26 with macOS Tahoe 26, Maybe .icon is not supported in UE 5.7?

Thanks!
