Purpose of the (dis?)like button in Orama chat

[krzysdz]

The button is a thumb down, is labelled as "Upvote response" and doesn't do anything (other than permanently setting the disliked state variable to true). I can't find any reference to upvoting or downvoting responses anywhere in Orama docs (here, here or here in sources).

What is/was this button supposed to do?

Lines 48 to 57 in a1db652

	<li>
	<button
	type="button"
	className={`chat-action ${disliked ? 'chat-action--disliked' : ''}`}
	aria-label="Upvote response"
	onClick={dislikeMessage}
	>
	<ThumbDislike16Regular width={18} height={18} />
	</button>
	</li>
