How do I get Message content on Samsung Galaxy S7 Edge Feed?

[AC Question]

My Edge Feed only tells me that I have messages. I would like it if the Feed also showed the content of the messages. For example, with Google Hangout, it actually displays the messages, not just informing me that I have some. I'm using the Samsung stock messaging app. Is there a setting I need to change, or is there a 3rd party messaging app that does display content in the Edge Feed? Thank you
