We are building an embedded map using the Sketch component and the JavaScript API.
All is working fine on desktop, we can draw a route, polygon, etc and we can delete a waypoint by using the mouse with a right click.
However on mobile there is no mouse to right click with.
You can see the issue when viewing the following example on a mobile device:

The "idea" therefore is to enhance the sketch widget to support deleting waypoints on mobile/touch only devices.
