Toast (UIWindow) not showing in SwiftUI

With .fullScreenCover I'm presenting a View (UIViewControllerRepresentable) which prompts toast message as a UIWindow but the toast message doesn't show up. If I call the same UIViewController from the UIKit app it shows the toast.

Is possible to show new UIWindow from the UIViewController modally presented from SwiftUI?
