How can I change my keyboard to a Samsung one?

I recently got an honour phone, specifically the magic8 lite, and it's great so far however the Microsoft SwiftKey and emoji keyboard (which just seems like an iPhone one to me) are just not for me. I made the switch but I loved the Samsung keyboard and don't want to part with it so is there a way I can get it onto my honour. I did see a video by Milan Tech Tips however the link that he states is in the description simply is not there or at least is not clear to see. Thank you in advance
