The description column for the click method is empty. This method should have a meaningful description explaining what it does and when to use it.

Suggested change

	| `click` | _None_ | `void` | |
	| `click` | _None_ | `void` | Programmatically triggers a click action on the list item. Use this method to simulate a user click or to invoke any click event handlers associated with the item. |
