I'm try use this package on lumen 5.4, but getting the following error:

FatalThrowableError in ServiceProvider.php line 45:
Call to undefined method Laravel\Lumen\Application::share()
in ServiceProvider.php line 45
at ServiceProvider->register() in Application.php line 174
at Application->register(object(LumenServiceProvider)) in app.php line 79
