Android shows data only notifications in tray

When I send a data only notification (no message, no title, just a data JSON) then it means I only want the app to receive the data. I do not want anything to show up in the notification tray.

On iOS this works as expected. On android I am getting empty notifications in the notification tray that just say my app name and that’s it.

Reproduce by just going here https://expo.io/notifications and only filling out the pushToken field and the JSON data field and send to an android phone.

How can I stop empty notifications like this from showing up in android?
