How do I display the free new level registration form?

Hi, I’m doing some tests in php and I’d like to be able to view only the free registration, that is this screen (https://i.imgur.com/6nEDxf8.png) so I tried the following code to call the page but it’s still not the specific page I need, could you help me with that? Can you give me any tips?

function exibir_conteudo_guia()
{
    // Verificar se o usuário tem permissões para acessar esta página
    if (!current_user_can('manage_options')) {
        return;
    }

    // Incluir o arquivo do PMPro que contém a tela de cadastro de níveis de associação
    require_once ABSPATH . '/wp-content/plugins/paid-memberships-pro/adminpages/membershiplevels.php';
}
