What function do you use to add buttons, links, and context menu items on forms and lists?

UI Settings refers to user preferences and display configurations, not a tool for adding interactive elements.

UI Actions provide a way to create client-side or server-side scripts that execute when a user clicks a button, link, or selects a context menu item on a form, list, or related list, allowing for custom functionality and interactions.

UI Policies are used to dynamically change the behavior of form fields (e.g., make visible, mandatory, read-only), not to add buttons or links.

"UI Config" is not a standard ServiceNow function for adding buttons, links, or context menu items.
