Couldn't find the definition of the element with tag 'app-layout-left-responsive' in any template file declared using '@JsModule'

Greetings!

I am trying to make a demo with this component. I use Vaddin 14.6.8, Spring boot 2.5.8 and app-layout-addon 4.0.0.
However, I am getting the following error. I have seen similar cases, but not seen the solution. Can you guide me?

Error:

There was an exception while trying to navigate to 'hola' with the exception message 'Error creating bean with name 'com.example.application.annotation.MainAppLayout': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.example.application.annotation.MainAppLayout]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Couldn't find the definition of the element with tag 'app-layout-left-responsive' in any template file declared using '@jsmodule' annotations. Check the availability of the template files in your WAR file or provide alternative implementation of the method getTemplateContent() which should return an element representing the content of the template file´.
