How do I know if a friend has turned down game invites?

Question

Classmates

The user's friend in the "Publicity Settings"->"Invite me to games" section chose not to invite anyone.
Now it turns out that the user sees him in the game, but cannot send him anything.
How can I find out if a friend has refused invitations to games and applications or not?

Answer 1

Ask a friend

Answer 2

There is no such opportunity for friends playing the game

Answer 3

maybe it's worth doing it?
it's just that in OK there are not enough requests that are in VK-FB and therefore it is difficult to work with it
