Why does the Guest role in group show in the collaborations and what does it do if I cut access for them in my game?

Hello!

Today, I thought that it would be good to give my group members access to play my game but I noticed the Guest role…

So here are my questions:

What will happen if I let it as “Play”? Will everyone (even non-members in my group) be able to join the game even when it is private?

What if I cut access (“No Access”)? Will nobody except my group members allowed to join, even if I would publish the game?

If you cut it to “No Access”, non-group members will be unable to play it.
If you do nothing, everybody can play it, but only if you set it to public.
