I'm new here and I am not a programmer , then I need your help .
I am testing instructions Manage teachers and students found here : https://developers.google.com/classroom/guides/manage-users
I tried to use authentication and scopes as they do here in PHP QuickStart : https://developers.google.com/classroom/quickstart/php
I run successfully quickstart.php sample, then it means that the composer is successfully installed, but I just can not run the code to //Enroll the student in the course due insufficient authentication scopes.
Error message:
Fatal error: Uncaught exception 'Google_Service_Exception' with message 'Error calling POST h_ttps://classroom.googleapis.com/v1/courses/559522327/students?enrollmentCode=2j1l21l: (403) Request had insufficient authentication scopes.' in C:\ProgramData\ComposerSetup\bin\vendor\google\apiclient\src\Google\Http\REST.php:110 Stack trace: #0 C:\ProgramData\ComposerSetup\bin\vendor\google\apiclient\src\Google\Http\REST.php(62): Google_Http_REST::decodeHttpResponse(Object(Google_Http_Request), Object(Google_Client)) #1 [internal function]: Google_Http_REST::doExecute(Object(Google_Client), Object(Google_Http_Request)) #2 C:\ProgramData\ComposerSetup\bin\vendor\google\apiclient\src\Google\Task\Runner.php(174): call_user_func_array(Array, Array) #3 C:\ProgramData\ComposerSetup\bin\vendor\google\apiclient\src\Google\Http\REST.php(46): Google_Task_Runner->run() #4 C:\ProgramData\ComposerSetup\bin\vendor\google\apiclient\src\Google\Client.php(593): Google_Http_REST::execute(Object(Google_Client), Object(Google_Http_Request)) #5 C:\Pr inC:\ProgramData\ComposerSetup\bin\vendor\google\apiclient\src\Google\Http\REST.php on line 110
Attempt to adapt the sample code:

} catch (Google_Service_Exception $e) {
if ($e->getCode() == 409) {
print "You are already a member of this course.

It's something to do with scopes and Google_Service_Classroom classes?
I will be very thankful if you can help me!
