OnExtraImageInteract

This event is called when the extra image associated with the input field has been interacted with.

using UnityEngine;

public class ChatBoxExample : MonoBehaviour
{
	// BE SURE TO ASSIGN THIS IN THE INSPECTOR //
	public UltimateChatBox chatBox;


	void Start ()
	{
		chatBox.OnExtraImageInteract += () =>
   		{
                	print( $"Extra image interacted." );
                	// Disable the input field. This is useful for the extra image being an "Enter" button for the input field.
                	chatBox.DisableInputField();
		};
		
		// OR //
		
		chatBox.OnExtraImageInteract += OnExtraImageInteract;
	}
	
	void OnExtraImageInteract ()
	{
		print( $"This also works! Extra image interacted." );
	}
