How to get user's RK list using Refresh Token (OAuth2)?
I installed this library - https://github.com/googleads/googleads-php-lib But I did not find any documentation on working using this particular method ... I
use this code:

function Auth() {
    session_start();

    $oauth2 = new OAuth2([
        'authorizationUri' => 'https://accounts.google.com/o/oauth2/v2/auth',
        'tokenCredentialUri' => 'https://www.googleapis.com/oauth2/v4/token',
        'redirectUri' => '***************',
        'clientId' => '***************',
        'clientSecret' => '***************',
        'scope' => 'https://www.googleapis.com/auth/adwords'
    ]);
    if (!isset($_GET['code'])) {
        // Create a 'state' token to prevent request forgery.
        // Store it in the session for later validation.
        $oauth2->setState(sha1(openssl_random_pseudo_bytes(1024)));
        $_SESSION['oauth2state'] = $oauth2->getState();

        // Redirect the user to the authorization URL.
        $config = [
            // Set to 'offline' if you require offline access.
            'access_type' => 'offline'
        ];
        header('Location: ' . $oauth2->buildFullAuthorizationUri($config));
        exit;
    }
    elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {
        unset($_SESSION['oauth2state']);
        exit('Invalid state.');
    } else {
        $d = $oauth2->setCode($_GET['code']);

        $authToken = $oauth2->fetchAuthToken();
        $oAuth2Credential = (new OAuth2TokenBuilder())
            ->fromFile()
            ->build();
        $session = (new AdWordsSessionBuilder())
            ->fromFile()
            ->withOAuth2Credential($oAuth2Credential)
            ->build();

        $adWordsServices = new AdWordsServices();

        $campaignService = $adWordsServices->get($session, CampaignService::class);
        define('PAGE_LIMIT',500);
        // Create selector.
        $selector = new Selector();
        $selector->setFields(['Id', 'Name']);
        $selector->setOrdering([new OrderBy('Name', SortOrder::ASCENDING)]);
        $selector->setPaging(new Paging(0, PAGE_LIMIT));

        $totalNumEntries = 0;
        do {
            // Make the get request.
            $page = $campaignService->get($selector);

            // Display results.
            if ($page->getEntries() !== null) {
                $totalNumEntries = $page->getTotalNumEntries();
                foreach ($page->getEntries() as $campaign) {
                    printf(
                        "Campaign with ID %d and name '%s' was found.\n",
                        $campaign->getId(),
                        $campaign->getName()
                    );
                }
            }

            // Advance the paging index.
            $selector->getPaging()->setStartIndex(
                $selector->getPaging()->getStartIndex() + PAGE_LIMIT
            );
        } while ($selector->getPaging()->getStartIndex() < $totalNumEntries);

        printf("Number of results found: %d\n", $totalNumEntries);
    }

In response constantly "Message: [AuthorizationError.USER_PERMISSION_DENIED @ ; trigger:'']"

I encountered it myself, maybe it will help someone: it is
necessary from the advertising account in which the company is set up to provide access to the managing account of the manager of advertising companies: TOOLS and SETTINGS -> Access settings and security
