I am making an attempt to create an InputAccessoryView/View pinned to the keyboard in SwiftUI with the next functionalities:

It must be pinned to the keyboard when it seems.
Tapping the view ought to open the keyboard.
When dragging the view down, it ought to increase vertically in direction of the navigation bar.
Whereas I’ve discovered some sources, I am uncertain about the most effective method to attain this.

May anybody present insights or share code examples on the best way to implement this successfully utilizing SwiftUI, probably combining it with UIKit for keyboard administration?
