How does group games and getting the owner of a group game work?

So I have a whitelist, and if the owner of a game with my stuff in it isn't on a pastebin, I will get a webhook of something like this: GAME LINK: (link of game) GAME OWNER: (link of place owner)

now I was testing this with a group game, and it didn't work, so how can I tell if a game is a group game or not Also, for some reason the game owner was shown as https://roblox.com/users/6030970/profile if anybody knows how this works and how I can check if the game is a group game and check the group owner, please tell me.

If it is a group game, you should be able to go to your group, and see the game in the games section of your group and to know the group owner you can click on the dropdown menu that shows ranks, and click the topmost one
