Module is not working with keycloak 26

Problem/Motivation

I have installed the module and found out that the scope "openid" is required for Keycloak 26.

Steps to reproduce

Install keycloak 26+ and the oauth keycloak module 2 on drupal 11.

Proposed resolution

Adjust the function by adding the scope openid in the source file KeycloakAuthManager.php:

  /**
   * {@inheritdoc}
   */
  public function getAuthorizationUrl(): string {
    $scopes = [
      'openid',
      'email',
      'profile',
    ];
