Where does the EULA need to be placed in an app?

I am developing an app I plan to release on the Google Play Store and the app store, and we are required to write our own EULA for it. Are there any requirements where it must be placed in the app, or can we simply have a button that links to the EULA on the website for the app?

It can be linked in the product description. I know the Google Play store has limited options. As an example, see https://play.google.com/store/apps/details?id=com.epicgames.TappyChicken&hl=en.

Tappy Chicken was removed from the store. Is there anywhere else where we can see an EULA example in the product description?
