Is it possible to detect where the swipe happens in Net MAUI? - xaml

Question

I'm writing a .Net MAUI application and am using SwipeGestureRecognizer. This is all working great. But what I can seem to find is if you can detect where the swipe occurred.
.xaml
<Grid x:Name="myGrid" >
<Grid.GestureRecognizers>
<SwipeGestureRecognizer Direction="Right" Swiped="SwipeGestureRecognizer_Swiped" />
</Grid.GestureRecognizers>
...
.xaml.cs
private void SwipeGestureRecognizer_Swiped(object sender, SwipedEventArgs e)
{
...
}
But I specifically want to detect if you swipe in from an edge, primarily so I can show a popout menu on the edge. I can see nothing in the event args (of the Swiped event that I could use to detect where the swipe happened.
Consider the image attached. How can I tell (or detect) the difference between the wholly on-screen swipe action (green) from the off-screen swipe action (red). Some location parameters would be perfect, but they don't seem to exist.
I can't see anything in the MAUI docs to suggest this is even possible
Does anyone know if there is any way to achieve this, please?
Thanks?

It's not an elegant solution but you can place an invisible BoxView on the left:
<Grid>
<BoxView
HorizontalOptions="Start"
VerticalOptions="Center"
WidthRequest="40"
Color="Transparent">
<BoxView.GestureRecognizers>
<SwipeGestureRecognizer
Direction="Right"
Swiped="SwipeGestureRecognizer_Swiped"
Threshold="25" />
</BoxView.GestureRecognizers>
</BoxView>
<!-- your content -->
<VerticalStackLayout Margin="15,0,0,0">
<Button />
<Label Text="label" />
</VerticalStackLayout>
</Grid>
I have decreased the value of Threshold because the swipable distance is small.
