I have problem with google drive api v3.
I took google example and I tried. I could read folder content but I did nothing with folder permission.

I received error 403, "Insufficient Permission".
I can't create or read all permissions for the folder.

<?php

require_once __DIR__.'/vendor/autoload.php';



$client = new Google_Client();

$client->setAuthConfig('client_secrets.json');

$client->addScope(Google_Service_Drive::DRIVE);

$client->setAccessType('offline');



if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {

    $client->setAccessToken($_SESSION['access_token']);

    $drive = new Google_Service_Drive($client);



    $folderId = '1_ip3-WUs4F6atNdElJ3KHccAV4lI0nLL';



    $optParams = array(

        'pageSize' => 100,

        'fields' => "nextPageToken, files(id,name)",

        'q' => "'".$folderId."' in parents"

        );



    $results = $drive->files->listFiles($optParams);



    if (count($results->getFiles()) != 0) {

        foreach ($results->getFiles() as $file) {

            echo "Id: " . $file->getId() . "  Name: " . $file->getName() . "<br>";

        }

    }   



} else {

    $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/oauth2callback.php';

    header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));

}



//+!+!+!+!+!+!+!+!+!+! Next code doesn't WORK  !+!+!+!+!+!+!+!+!+!+!+!+!+!+!+!+!+!//



$fileId = '1UXSg5W-XIX82izGK8uEXXWPUCLcDGRa1';



$userPermission = new Google_Service_Drive_Permission(array(

    'type' => 'user',

    'role' => 'reader',

    'emailAddress' => 'email@gmail.com'

    ));



$request = $drive->permissions->create($fileId, $userPermission, array('fields' => 'id'));

echo $request; 



?>

It may be that wrong permissions have been set when creating the folder, even though you said you did nothing. I do not see the code for creating the folder here, just an ID, which indicates that the folder has already been created.

I suggest trying to list the permissions using Drive.Permissions.List first. Particularly, look at the type and role or teamDrivePermissionDetails.role properties. See the permissions guide on what operations each role or type can do. You can also visit this documentation on managing sharing in case you need to.
