PKToolPicker in SwiftUI

I am trying to use PKToolPicker (from PencilKit) without a PKCanvasView by adopting PKToolPickerObserver in my own class.

I am wondering how to deal with the FirstResponder required by PKToolPicker visibility set from a SwiftUI App when the view containing the PKToolPicker is a UIViewRepresentable embedded in a SwiftUI View that has control of gestures.

Thanks in advance,
