How to enable custom transitions between screens?

I am using onPress={() => navigation.navigate('MyScreen')} to navigate between screens in my App and due to design requirements it would be necessary to have different transitions on some of them rather than the global one declared in <Stack.Navigator screenOptions...

How can I do this? - I don't see how to or that is not possible in the documentation.

Start by locating the documentation for the Stack.Navigator screenOptions and the navigation.navigate entry point mentioned in the issue. Document how to configure different transitions for individual screens, with an example showing a screen-specific transition alongside the global setting.
