How to Make keyboard slide up in XD?

Hello,

I am new to XD and am trying to prototype an app design I made but I can't figure out how to do what I want to do. So I have a new post page and it says "write caption" and I want to click on that and a keyboard slide up. When the keyboars slides up I want the page header to change from "new post" and "Post" to "caption" and "ok", but it doesn't look like I can have two overlays at the same time. Is there another way to create this look?
