Arrows/annotations on scattermapbox

Hi

I need to draw an arrow specifying the direction of travel for a vehicle (refer to image below). I am using scattermapbox to plot this. I want to draw an arrow instead of a normal line.
I know for a normal scatter plot this could be achieved using annotations (Arrows between markers joined at the edges). Can same be done for scattermapbox plots as well. Please help!
