If lines of text exceed the size of the text placeholder the button displays on the left side of the slide?

If lines of text exceed the size of the text placeholder, the button on the left side of the slide typically indicates that there is more content available. This could mean that the text is either truncated or hidden, prompting the user to take action, such as clicking the button to view the full text. It's important to ensure that the design remains user-friendly and that any additional content is easily accessible when needed.
