How to test a REQUEST GET in Acceptance Test - yii2

Question

I am testing a script for logout and access a URL not accessible when you are not logged in, but in my URL LOGOUT, i get the response code 405 and this is problematic.
Code:
$I = new AcceptanceTester($scenario);
$I->amOnPage('/financeiro_legado/finlegado-titulo/index');
$I->wantTo('Logout');
$I->amOnPage('/');
$I->fillField('LoginForm[username]', 'marcelo');
$I->fillField('LoginForm[password]', 'marceloid5123');
$I->click('#login-form .btn');
$I->see('Olá, marcelo');
$I->seeInCurrentUrl('/');
$I->click('Logout', '.nav');
$I->amOnPage('/financeiro_legado/finlegado-titulo/index');
Returns:
Logout (LogoutCept)
Scenario:
* I am on page "/financeiro_legado/finlegado-titulo/index"

Probably you handle that click with Javascript in the web browser.
Yii2 module of Codeception does not execute Javascript.
Your options are:
a) make your site work with Javascript disabled.
You could achieve that by changing
Logout
To
<form method="POST" action="site/logout">
<input type="submit" value="Logout" />
</form>
b) Use sendAjaxPostRequest method to make POST request
$I->sendAjaxPostRequest('site/logout', []);
