How Do You Attach A Live Link For Videos With Aol Email?

My friend is having issues with attaching videos to the emails she sends out. She would like for them to be clickable, so her friends doesn’t have to copy and paste. I know with Yahoo!, there’s a hyperlink icon, but I just tried to sign into AOL and I don’t see anything of the sort. So, how do you attach live links to an AOL email?
