To draw text on the side of a UITextView, you can utilize the new text formatting features introduced in UIKit. Specifically, you can customize the text formatting panel by setting a custom UITextFormattingViewControllerConfiguration using the UITextView's new text formatting configuration property. This allows you to tailor the presentation of the panel and apply text highlight styles and color schemes.
