+/**
+ * Microsoft365 allows authentication via Microsoft365 OAuth2 flow.
+ * Before using Microsoft365 OAuth2 you must register your Microsoft Azure Application
+ * @see https://portal.azure.com
+ *
+ * Note: the registered App must have the following:
+ * -Authentication: 'Redirect URIs' set 'user/security/auth?authclient=microsoft365' as an absolute URL
+ *  e.g. https://domain.com/index.php/user/security/auth?authclient=microsoft365
+ * -API Permissions: 'Microsoft Graph' > 'User.Read'
+ * -Decide whether the App should be
+ *   single-tenant (only allow one Company to use it),
+ *   multi-tenant (also allow other Companies to use it),
+ *   personal account (allow accounts like xbox, skype etc. to use it)
+ *   or both "multi-tenant and personal-account"
+ * -In the Microsoft world even the Authorization URls are different dendinding if you allow single/multi/personal accounts.
+ *  This client supports them: just set up the 'signInAudience' property (value for this it's in the manifest of your Azure App)
+ *  accordingly to your needs; it defaults to the widest permissions available "AzureADandPersonalMicrosoftAccount"
+ *  (details: https://learn.microsoft.com/en-us/entra/identity-platform/supported-accounts-validation)
+ *
+ * Example application configuration:
+ *
+ * ```
+ * 'components' => [
+ *     ...
+ *     'authClientCollection' => [
+ *         'class' => 'yii\authclient\Collection',
+ *         'clients' => [
+ *             'microsoft365' => [
+ *                 'class' => 'yii\authclient\clients\Microsoft365',
+ *                 'clientId' => 'a5e19acd-dc50-4b0a-864a-d13b9347ddf9',
+ *                 'clientSecret' => 'ljSAd89.lvk34NV-3t4v3_2kl_42Rt4klr234',
+ *                 'signInAudience' => 'AzureADandPersonalMicrosoftAccount',
+ *             ],
+ *         ],
+ *     ]
+ *     ...
+ * ]
