If you don't want to listen every event use getDocuments method instead of addSnapshotListener. 

/// This will give you team data
document.data()["team"]

After getting the team information from firestore. Here is how to get name and officeId:

if let teamInfo = document.data()["team"] as? [String: Any] {
   let teams = teamInfo.map {$0.value}
   for team in teams {
       guard let validTeam = team as? Dictionary<String, Any> else {continue}
       let name = validTeam["name"] as? String ?? ""
       let officeId = validTeam["officeId"] as? String ?? ""
       print("name: \(name), officeId: \(officeId)")
   }
}

Output

name: Developer Ratufa, officeId: myuPlTBO8sEM4SOQ8rWY
name: , officeId: myuPlTBO8sEM4SOQ8rWY
