Using Sharing Panel in a iOSContainerControl in a iOSScrollableArea

I have a view (ViewDiff) with has a iOSScrollableArea. The iOSScrollableArea’s contents is a iOSContainerControl. This iOSContainerControl has a canvas “cvSharing”.

Canvas cvSharing:
Sub PointerDown(pos As Xojo.Core.Point, eventInfo As iOSEventInfo) Handles PointerDown
dim sh as new iOSSharingPanel
dim n as new ViewDiff
// ShareText(textToShare As Text, parentView As iOSView, parentControl As iOSControl)
End Sub

If I run this app in debug mode, no sharing will be activated. How can I use the sharing panel from a iOSContainerControl?
