Show the Social Marketing ad in every posts automatically

How can I show the Social Marketing ad in every posts automatically? For example, at the end of the posts, or at the very start of the post content?

Another question:
On this screenshot https://premium.wpmudev.org/project/social-marketing/installation/ , there is a "Popup box" setting, which allows you to select "Colorbox", but I don't see this setting in my plugin?

Thanks.
