I am using Ionic and everything is configured to send the notification...
I wanted to increase the importance of it because it does not make noise and does not appear in the upper corner as a standard notification (like Whatsapp)
How can I increase notification importance using the Firebase Cloud Messaging API
Actually no, I’m using the phone-gap push Notifications

in this case the property is called "importance". https://github.com/phonegap/phonegap-plugin-push/blob/master/docs/API.md#Channel-properties
