Click and hold on the mask button to get a menu with the other mask tools.
The mask tools have changed a couple of times over Hitfilm's life.
With HF 15 the two mask icons you see in older tutorials got combined to a single icon. As Ben Norris said, click and hold on the single icon and a submenu will give you the choices of rectangle and circle masks - AND new rounded rectangle and polygon mask options! 😁
