Activedocs Red Exclamation Button for Authorization Not clear

ActiveDocs for an API displays only a red exclamation button when Authorization is required. Clicking on the Exclamation button brings up the pop with title "Available Authorizations" for OAuth 2.0 . Displaying only the button does not help the developer to understand that the exclamation button is meant for Authorization. Displaying a label ( or equivalent ) indicating that this button is for Authorization would be helpful.
