How to limit the visibility of an element on the page depending on the role?

Question

Spring

Greetings. I am writing a web application on Spring boot, Thymeleaf and faced the need to limit the visibility of some interface elements on the page. I have welcome.html, where for the admin I want to display elements for managing the CRUD entity of the software, and if the user role is not admin, then no.

Spring security is set up. The project can be viewed here https://github.com/MarkusEfr/Market.
How is this problem solved within this framework?

From documentation :

<div sec:authorize="hasRole('ROLE_ADMIN')">
  This content is only shown to administrators.
</div>
