This allows you to change the text in your buttons.
The text on your CTA buttons is supremely important. It lets people know what action they are going to take and how it will benefit them. Visitors to a website often "convert" as a result of clicking a button.
Therefore it is pretty important that visitors clearly understand what the text in a button means. Your visitors may interpret the button texting differently from what you intended, so it is important to test out what text works the best
Text can also encourage (or even discourage) a visitor to click on certain buttons. For example, for buttons that you would like your visitors to click on, having text that outlines the benefits (e.g "Get 50% Off") will make them more likely to convert. For buttons that you would not like your visitors to click on, having text that outlines that disadvantages (e.g "Lose 50% Discount") will discourage them from clicking.
