How to use the @loopback/authentication.AuthenticationBindings.CURRENT_USER function in @loopback/authentication

constructor(
    // The provider is instantiated for Sequence constructor,
    // at which time we don't have information about the current
    // route yet. This information is needed to determine
    // what auth strategy should be used.
    // To solve this, we are injecting a getter function that will
    // defer resolution of the strategy until authenticate() action
    // is executed.
    @inject.getter(AuthenticationBindings.STRATEGY)
    readonly getStrategy: Getter,
    @inject.setter(AuthenticationBindings.CURRENT_USER)
    readonly setCurrentUser: Setter,
  ) {}
