presentCover(:onDismiss) now gone, how now to invoke a closure up on dismissal?

[Scvairy]

There are some relics of older api with onDismiss mentions, but no actual closure is accepted.

Using a method mentioned here:

is too bulky in case when I want to invoke onDismiss for a certain screen I pushed from certain place.

How can I maybe rewrite it, so I would affect only the screen I presented with routes.presentSheet(.myScreen)?

I've found workaround to call my onDismiss in buttons, but on swipe down it will not be called.
