Is there a way to convert iced_native::overlay::Element into iced_native::Element?

[Amazingkenneth]

I want to implement multiple selection button over a map image. Like this:

The red dots are buttons for selecting positions on the map, which can be implemented by setting iced_native::widget::image at the background. Currently, it seems like you can implement the button effect by creating iced_native::overlay::Group, but there is no way to convert overlay::Element to native elements, which seems unreasonable and prevents me from inserting code into view() to display them.

I tried iced_aw::native::floating_element::FloatingElement, but it allows only one element to be bound to an overlaying element. (see iced-rs/iced_aw#120, I closed the issue after I realized that reassigning to FloatingElement would not work)

Is there any way I can implement this?
