Paypal api – File upload to google drive with service account authentication successful but not missing

I am trying to upload a zip file to google drive with a php script as a cron job on Fedora 33 x86-64. I have been tried several different things but I am not having any luck with this at this point. I have created a service account and downloaded the credentials, created the oauth concent screen, installed the Google Drive API, oauth client id, etc… Anyway when I run the script from the shell I get a very strange. Any help would be appreciated.

<?php
    require_once 'vendor/autoload.php';
    $googleClient = new Google_Client();
    $googleClient->setAuthConfig('***************************.json');
    $googleClient->addScope(Google_Service_Drive::DRIVE);
    $googleClient->setApplicationName('******************');
    $googleClient->setAccessType('offline');
    $googleClient->getAccessToken();
    $drive = new Google_Service_Drive($googleClient);
    $file = new Google_Service_Drive_DriveFile($googleClient);
    $file->setName('Mysql-Backup.zip');
    $file->setMimeType('application/zip');
    try {
      $return = $drive->files->create($file, array('data' => file_get_contents("Mysql-Backup.zip"), 'uploadType' => 'multipart', 'supportsAllDrives' => 'true'));
      echo "Sucessful upload of " . $file['name'] . ".";
    }
    catch (Exception $exc) {
      echo $exc->getMessage() . "n";
    }
?>

Forgive me if I am not doing this correctly both the code and posting on stackoverflow.com. Ok I have tried as you suggested listing the files and you are indeed correct that the files were uploaded to my service account instead of my personal drive. I have also tried your suggestion of sharing a folder from my personal account to the service account using the web interface. However when I try again it still isn’t working. This gives me an error "PHP Fatal error: Uncaught Error: Call to undefined method Google_Service_Drive_Resource_Permissions::insert() in /scripts/google-drive/google-drive.php:25". I have refereed to https://developers.google.com/resources/api-libraries/documentation/drive/v3/php/latest/class-Google_Service_Drive_Permission.html and https://developers.google.com/drive/api/v2/reference/permissions/insert#php but still I don’t understand what I am missing. I don’t know if this is frowned upon but I am willing to paypal someone if they have a currant working php class with instructions. The documentation for this is all over the place the old stuff doesn’t work and the new stuff doesn’t work. I am banging my head in at this point.
