In the checkout process, How to alter the "confirm button"

Dear Sir, greetings.
Greetings, Sir. My account was created, and I have a few questions about OpenCart. In step 6 of the checkout process, I want to change the "Confirm Button.". There is a "confirm order" button on the right side; I want to alter this button, but I'm not sure how. Make sure this is true.
Thank you for considering my request.
