 Here are two examples on how to use these methods:
 
 .. code-block:: javascript
 
     // note that we call _t on the text to make sure it is properly translated.
-    this.do_notify(_t("Success"), _t("Your signature request has been sent."));
-
-    this.do_warn(_t("Error"), _t("Filter name is required."));
+    this.displayNotification({
+        title: _t("Success"),
+        message: _t("Your signature request has been sent.")
+    });
+    this.displayNotification({
+        title: _t("Error"),
+        message: _t("Filter name is required."),
+        type: 'danger',
+    });
