As-is

• Clicking upvote / downvote shows reason dialog.
• Upvote / downvote are sent along with its reason after clicking "Send".

To-be

• Upvote / downvote (without reason) is submitted as soon as the upvote / button button is clicked.
• Clicking upvote / downvote still shows reason dialog, but with different prompt: "Thank you for the feedback." + "Do you have anything to add?" / "Why do you think it is not useful?"
• "Send" --> "Close" when no content, "Send" when inputted something
• After clicking "Send", the vote is submitted again, this time with reason.
