login method

Future<AuthenticationResponse?> login(LogbotCredentials credentials, { String? otp, })

Log in with a user, saves the credentials and tokens on the client to refresh the access later

Implementation

  String? otp,

  }

  /// it again. Will just return the Future and everyone will wait for that
