How do I recover GIF on my keyboard with the # sign? I lost it somehow

[AC Question]

On my Samsung Galaxy S6 Edge I used to be able to hit the # sign & all categories of GIF's would be shown at the top of my screen. I could choose a GIF & add a message and send it in a text message. I updated my phone & when I hit the # sign button no GIF appear. That feature came with my phone. How do I recover it or add it back to my keyboard ?
