An idea to add an AccessToken to EnvironmentValues in the SwiftUI.

EnvironmentValues+AccessToken.swift

import SwiftUI

extension EnvironmentValues {
    struct AccessTokenKey: EnvironmentKey {
        static var defaultValue: String? {
            nil
        }
    }

    var accessToken: String? {
        get {
            self[AccessTokenKey.self]
        }

        set {
            self[AccessTokenKey.self] = newValue
        }
    }
}
