[Question] Anybody Know How to Attach Link Under FB Video Player

As recent updated from fb, I really can't find Power Editor to do so.
It looks like they move to or remove this feature.

What I really want to ask if anybody can help show how to embed the link of our website to the video player under mobile device.

I found someone here post it everyday along the fb groups I am member with.

Please take a look to my screenshot from my iphone captured below:

Thanks in advance,
