Open external app without UrlScheme

[Colir]

Hello,
I am trying to open an external app from my Flutter app on iOS.
The external app does not provide URLSchemes in its info.plist.

The idea is just to open the app without deep linking.

How can I do that?
thanks

I would say its not possible.
The called app needs so accept this call.
Even if no data is given, it has to implement a call handler.
