This is how the buttons in all modals should look like by the current design. It is not always like this because this convention came into place later in development.
Alternative #1
Same setup as the current design, but spaced out a bit more.
Alternative #2
Same setup as #1 but with a bold link, and a different hover effect.
Alternative #3
More prominent cancel button. Note that very few modals have a button in place of the secondary action. Toggle secondary action.
