+In this example, the `applicationServerKey` variable contains the VAPID public key,

+convert-vapid-public-key package. The options object is of type PushSubscriptionOptions,

+The VAPID (Voluntary Application Server Identification) key provides more security and
+authenticity for web push notifications in the following ways:
+
+    Identifying the Application Server:
+    
+        The VAPID key is used to identify the application server that is sending the push notifications.
+        This ensures that the push notifications are authentic and not sent by a malicious third party.
+	
+    Encrypting the Messages:
+    
+        The VAPID key is used to sign the push notifications sent by the application server,
+	ensuring that they are not tampered with during transmission. This provides an additional
+	layer of security and authenticity for the push notifications.
+
+Adding Contact Information:
+
+    The VAPID key allows a web application to add contact information to the push messages sent to the browser push service.
+    This enables the push service to contact the application server in case of need or provide additional debug information about the push messages.
+
+Improving Delivery Rates:
+
+    Using the VAPID key can help improve the overall performance of web push notifications, specifically improving delivery rates.
+    By streamlining the delivery process, the chance of delivery errors along the way is lessened.
