Popup addon doesn't show

I tryed to use the popup addon in Vaadin 23…
I tryed to use ad target a button and a VerticalLayout but it doesn’t show anything.
I tryed using both setIgnoreTargetClick false and true but again nothing happens.
What’s wrong ?
Tks

Target and the Popup should be added to the same parent component (and the same applies to Popover of Vaadin 24.6)
