How do I get the group status of a group for display in-game

What I’m trying to do is get the shout of a group and display it in-game. The thing is I don’t know-how.
I tried the method listed here: Support shout retrieval in group web API but I couldn’t figure out how to use it

Also, there is no Roblox API for getting group shouts. So how do I do this because I have seen some games that can get the status (shout) of a group
