MapKit for SwiftUI iOS 17 - deselect Selected Marker

I am testing using MapKit for SwiftUI on iOS 17.

I can select an Marker and when selected, that Marker gets bigger as expected. However, I would like to display a custom view for the selected Marker. I can display that custom view and dismiss that view when user selected the "dismiss" button.

But, the Marker remains big (as selected). How to dismiss it without user interaction?
