Now the mendix studio/app store does not have a push notification for web app.
The solution I found was using onesignal free app. It is really simple to use and already have integration with wordpress for example:

HI Emerson, we do have an option to integrate with Pusher: https://docs.mendix.com/appstore/modules/pusher
Would that have helped?
