Not sure why Swat said to add people, as that's optional, but straight from the Help Article: [quote]Joining a Fireteam Before joining a Fireteam, players must be signed into their account on Bungie.net or the Destiny Companion App to join a Fireteam, and signed into their console or PC to receive invitations. To join a Fireteam, players need to go to the Find Fireteam area, select the Fireteam they'd like to join, and press the "Join Fireteam" button. Players must select which character they'd like to use. Once the Fireteam leader has closed the Fireteam, players will receive a notification on Bungie.net or the Destiny Companion App to join, and the Fireteam leader can send an invitation to the players in the Fireteam to their console or PC. [b]PLEASE NOTE:[/b] Players who didn't receive an invitation may need to adjust their platform's privacy settings. For example, players on PS4 must set their "Messages" privacy setting to "Anyone".[/quote] Source: https://help.bungie.net/hc/en-us/articles/360048721772-Finding-and-Creating-Fireteams *Edited to add, if you have multiple accounts linked your join code won't work, so keep that in mind.
