Usage guidelines
Use the disclaimer modal if the user must choose one of, at least, two actions in the modal to continue onward. The user should still be able to exit the modal by clicking anywhere on the overlay background. Clicking on the overlay background is the equivalent of taking the “Cancel” action or a non-destructive action, usually the secondary action.
With logo
It is only acceptable to add a logo in a modal if something is covering the logo on the modal’s parent page.
