How to enable swipe to dismiss on a transparentModal?

[u840903]

I've got a transparentModal in React Native (expo app router)...

<Stack.Screen
	name="modal"
	options={{
		presentation: "transparentModal",
		animation: "fade",
		headerShown: false,
	}}
/>

...that looks just like intended, but it doesn't behave like I want it to. I want to be able to dismiss it by swiping down. If I change to presentation modal I get the behaviour I'm after (at least when it comes to the dismiss swipe), but not the design.

• How can I get the behaviour from modal and the presentation from transparentModal?
• If swipe to dismiss has been intentionally disabled on transparentModal. Is there a reason for it?

I'm using...
"@react-navigation/native-stack": "^6.9.26",

So far I've tried...
gestureDirection: "vertical",
gestureEnabled: true,

... and doing a custom implementation of swipe to dismiss inside my modal. This works, but mine is not as good as the one in presentation:modal...
