AddGlobalNavigationObserver equivelent for IDialogService?

[MartinRobins]

Within the later versions of Prism, you can add a reference to the Prism.Maui.Rx package and then use the AddGlobalNavigationObserver method on the PrismAppBuilder to capture any errors that occur when navigating between pages using the INavigationService.

I currently have a problem where I am trying to use IDialogService.ShowDialogAsync to show a dialog. The dialog shows correctly on Android, but does not show at all on iOS and I am trying to see if I can find the reason. Since the call to IDialogService.ShowDialogAsync never returns I cannot use the Exception property of the IDialogResult, so I am hoping there may be something similar to the AddGlobalNavigationObserver that I can use to intercept any errors.

Note: There appears to be no output to any of the ILogging receivers configured either!
