(closed) Thymeleaf Security (sec:authorize tag) doesn't work in Spring

I have a problem: when I implemented thymeleaf security, added dependency, I noticed that sec:authorize tag isn't even working!
I've browsed a lot of questions, but all of them obsolete or man forgot to add dependency
This tutorial is so easy, there weren't any additional classes and configurations, but it didn't help either: https://www.baeldung.com/spring-security-thymeleaf

My project on github: https://github.com/sedub01/CafeBarApplication, I haven't push new changes yet (if you'd noticed some files missed, I'll add them)
There is my pom.xml file

Last, but not least: my html code:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
    xmlns:sec="http://www.thymeleaf.org/extras/spring-security">

<head>
    <title>Cafe Bar</title>
</head>

<body>
    <h3 th:text="'Welcome' + (${fullname} ? ', ' + ${fullname} + '!' : '')" />
    <img th:src="@{/images/cafeIcon.png}" />
    <!-- TODO think about placing in header -->
    <form method="POST" th:action="@{/logout}">
        <input type="submit" value="Logout" />
    </form>
    <div sec:authorize="!isAuthenticated()">
        This content is only shown to unauthenticated users.
    </div>
    <div sec:authorize="isAuthenticated()">
        This content is only shown to authenticated users.
    </div>
    <div sec:authorize="hasRole('ROLE_ADMIN')">
        This content is only shown to administrators.
    </div>
    <div sec:authorize="hasRole('ROLE_USER')">
        This content is only shown to users.
    </div>
</body>

</html>

Actual result (I've logined as USER, but every div is displayed):

As you using spring-boot version 3.1.0 which uses spring 6.0.9 version. But the library you have used thymeleaf-extras-springsecurity5 is using spring version 5.x so it will not work as expected.

Use the thymeleaf-extras-springsecurity6 library instead.
