Thank you anyway sir. I just wanted to ask you about steamcommunity postUserComment here is the code : client.on('friendRelationship', (steamID, relationship) => {if (relationship === SteamUser.EFriendRelationship.RequestRecipient) { client.addFriend(steamID); client.inviteToGroup(steamID, config.groupid, ); community.postUserComment(steamID, "Thanks for adding me ! I wish you good day."); it is doing nothing, can you tell me how to callback ??Please help me it's not working
