I'm looking at the new beta features for MapKit in SwiftUI, does anyone know if it's possible to create a map annotation callout or popover from a custom view?
SwiftUI MapKit Custom Callout
There's no supported way for you to create a selection accessory callout displaying a custom view with the APIs currently available. If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Please share as much information as possible about your use case. Once you file the request, please post the FB number here.

Thank you for the clarification, I will file an enhancement request.
