Apple - What shortcut does ⌦ symbol in Camunda macOS app indicate and how to invoke it?

In macOS, this symbol represents forward delete shortcut (to delete characters to right). It can be generated using the fn + delete key combination.

• ⌫: Delete Left (like Backspace on Widows/PC)

• ⌦: Delete Right (fn + delete on compact keyboards. Also called Forward Delete)
