Dismiss Page actions return the user to the previous page from their current page. Dismiss Page actions inherit the action settings of the Open Page action that took the user to that page. As such, Dismiss Page actions will not fire unless the user has already navigated to the page using an Open Page action.
Choose the action’s easing curve: Default, Linear, Ease In, Ease Out, Ease In & Out, Spring, and Custom (write your easing curve using the Expression Editor).
