Creating dashed lines along an arrow's tail using geometry nodes

Question

This answer on how to programatically create an arrow that forms along a curve is very useful.

I would like to know how to convert the arrow's tail into a dashed line, as shown below, but keeping the properties of a geometry node, so the arrow is easily editable.
