Receive but let widget callback pass through ?

Hello,

Is there a way to receive widget input callbacks, but let those callbacks pass to the widget below even if the widget is set to EVisibility::Visible ?

If I set the widget to EVisibility::SelfHitTestInvisible I do not receive the input events anymore. If I set the widget to EVisibility::Visible the events are not forwarded to the widget below even when returning FReply::Unhandled();

void SCogImguiWidget::Construct(const FArguments& InArgs)
{
    [...]
    SetVisibility(EVisibility::Visible);
    [...]
}

FReply SCogImguiWidget::OnMouseButtonDown(const FGeometry& MyGeometry, const FPointerEvent& MouseEvent)
{
    DoSomething();
   
    // Unhandled does not forward the even to widgets below
    return FReply::Unhandled(); 
}

Thanks!
