Issue
Accessing [UIApplication sharedApplication].delegate.window in a scene-based life-cycle app results in a runtime crash, because the window property is not populated by default. The window property is accessed in RNFBMessaging+NSNotificationCenter.m at line 81 and 153. The scene-based life-cycle is available since iOS 13 and will be required soon for all apps. See this technote for further details.
As a quick fix, we can test if the delegate responds to the window selector, before comparing it with != nil, to prevent the crash. But this approach prevents getting the React root view, which is used later to store the isHeadless property. I am not sure if this breaks the functionality of the messaging module in some way.
