+ * @Title: WebKitInstallMissingMediaPluginsPermissionRequest
+ * @See_also: #WebKitPermissionRequest, #WebKitWebView
+ *
+ * WebKitInstallMissingMediaPluginsPermissionRequest represents a request for
+ * permission to decide whether WebKit should try to start a helper application to
+ * install missing media plugins when the media backend couldn't play a media because
+ * the required plugins were not available.
+ *
+ * When a WebKitInstallMissingMediaPluginsPermissionRequest is not handled by the user,
+ * it is allowed by default.
+ *
+ * Since: 2.10
