How do I save a video from Gmail to my gallery?

[AC Question]

My friend sent me a video from her iphone, I've saved it to my "drive" and I've downloaded it, but I can't seem to get the video into my camera roll from the email. I've tried going to "my files" and I don't know what else to try, help!
