What is the latest push notification extension?

Show us the links of the Push Notification components. There are many notification extensions, see what you want in Pura Vida Apps Extensions. The simpliest, Taifun Notification, only supports devices below Android 8. Also, I love this Notification Style extension from @Jarlissonlira2. See a list of notification extension links here.
