Google API list reviews – 403 forbidden

I’m trying to implement fetching Google reviews for my business in Laravel using google/apiclient but I keep getting response code 403 Forbidden after my GET request.

        $client = new GoogleClient();
        $serviceAccountKeyFilePath = storage_path('key-json.json');
        $client->setAuthConfig($serviceAccountKeyFilePath);
        $client->addScope('https://www.googleapis.com/auth/business.manage');
        $client->setRedirectUri('http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php');

        $accessToken = $client->fetchAccessTokenWithAssertion();

        if (isset($accessToken['access_token'])) {
            $client->setAccessToken($accessToken['access_token']);
        } else {
            return;
        }


        $clientID = 'my-client-id';
        $placeID = 'my-place-id';

        $httpClient = $client->authorize();
        $url = 'https://mybusiness.googleapis.com/v4/accounts/' . $clientID . '/locations/' . $placeID . '/reviews';

        $response = $httpClient->get($url, [
            'headers' => [
                'Authorization' => 'Bearer ' . $accessToken['access_token'],
                'Accept' => 'application/json',
            ],
        ]);

        dd($response);

I enabled these APIs in my account:

• My Business Account Management API
• My Business Business Information API
• My Business Place Actions API
• Places API
• Places API (New)

But still I keep getting this

GuzzleHttpPsr7Response {#1670 ▼
  -reasonPhrase: "Forbidden"
  -statusCode: 403
}

I’m kinda confused and I can’t see what I am missing here.
