(Swift) Do realm.beginWrite/commitWrite need to be on the same instance of "let realm = Realm()"?

Sorry about the title, i’m not quite sure how to stay this succinctly. In any case, in my (iOS/Swift ut not SwfitUI) app, the user can edit an object (for example Team) over a number of screens. When I first start, I create a team using

// Team is subclass of Realm Object
let team = Team()

let realm = try Realm()
// save copy of team into a property or something in memory
realm.beginWrite()
    realm.add(team)
}

and then later in the app, after a number of interactions with the user:

var team = // fetch copy of team from memory
let realm = try Realm()
team.name="bar"
// other updates to "team".
try realm.commitWrite()

This seems to work fine, however I was just wondering if this is “OK” to do since I’m calling beginWrite and commitWrite in different calls to let realm = Realm().

I’m sure that the user has not and will not perform any other realm queries/writes during this flow since if the user “cancels” out of editing the “team”, I call realm.cancelWrite.

Thanks!

A more detailed example of what I’m going looks like this:

class MyViewController: UIViewController {
    private var team: Team?

    @IBOutlet weak var nameTextField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        do {
            // setup realm configuration up here somewhere
            let realm = try Realm()
            realm.beginWrite()
            let team = Team()
            realm.add(team)
        } catch {
            print("Error: \(error)")
        }
    }


    @objc func submitTapped(_ sender: Any) {
        let name = self.nameTextField.text!.trim()
        guard let team = self.team else {
            return
        }
        do {
            let realm = try Realm()
            self.team.name = name
            try realm.commitWrite()
        } catch {
            print ("Error: \(error)")
        }
    }
}
