How do I accept one friend request instead of accepting everyone?
Accept friends handles the bot's pending friend requests as a group. To approve one person, use that person's accept action in Requests instead.
Check the requester
Open Friends and inspect the displayed name and Epic ID on the intended request. Do this before using any bulk action.
Choose one action
Use the checkmark for that entry to accept it, or the decline button if you do not want that request accepted.
Invite separately
Friendship does not put everyone in one party. After the relationship updates, invite the bot from your real player's Fortnite friends list.
