How do you make a link to like a youtube video?

I have been looking through the html code on a youtube video to try to figure out how to trigger likes to a video but to no avail.

I want to make an invisible iframe with the like video link over a video shared to a website so that when people try to click the play button they instead like the video.

Is this possible with youtube? Ive seen similar things done with Facebook likes.

It should exist a few apps for this, how good they are idk
