Error on integrating Primefaces with Springboot/JoinFaces

Question

I´m trying to create an application that integrates primefaces with spring boot following these tutorials:

https://medium.com/@tsepomaleka/integrating-spring-boot-with-java-server-faces-using-joinfaces-297e64f6a28f

https://codenotfound.com/jsf-primefaces-example.html

And i added the joinfaces as the tutorial suggests:

This is my pom.xml

</project>

And i created the webapp/WEB-INF folder structure:

As you can see on the image the webapp folder doesn't look like that is recognized by intellij.

Other problem is that the xmlns:p="http://primefaces.org/ui" url taglib is not being recognized as you can see on the image.

So when i run on the browser: http://localhost:8080/eleicao.xhtml The browser returns me an error:

There was an unexpected error (type=Not Found, status=404). /eleicao.xhtml Not Found in ExternalContext as a Resource

So how can i resolve this? So that i can run primefaces pages.

You are missing a bunch of depenedencies here is my pom for PrimeFaces, MyFaces for JSF, OmniFaces, and Undertow as the servlet engine
