Youtube Mobile Annotations

[onlinemoneylove]

How is this channel able to flawlessly create mobile annotations. If you notice at the end of the video he's able to create mobile annotations right on the video linking to other videos and channels. He's definitely not using Info cards because if you notice their is no "i" at the top right corner. And also definitely couldn't be using regular annotations as those are not clickable on mobile devices. I tried everything and can't figure it out. Any input would be great thanks.
I don't think I can add links so here is the title of the video.

With the amount of views this channel gets I'd be surprised if no one caught on to this before

I don't get it, is this some kind of sick fetish niche? It seems very deranged, who would want to get involved in this for ANY amount of money?
