I'm trying to have my application open for a specific protocol. For this I set up the player settings for the protocol and when I open an URL the application gets started succesfully, so that part is fine. However I'm at loss how to get the callback with the Url within Unity. I read about the OnActivated event that can be overridden in the VS project. But how can I add this functionality to my unity c# code, so that I don't have to manually edit the VS project for each build? Here https://docs.unity3d.com/Manual/windowsstore-appcallbacks.html it is mentioned, that unity subscribes to most of the callbacks, also for Activated. However I have no idea how to subscribe to these now. Any help or hints would be appreciated!
