In the Firebase Console it is possible to target devices using a specific app, language, version and user properties. Is it somehow possible to do the same with the API? Or is creating topics the only way to solve bulk sending notifications?
Basically what I would like to do is send a notification to all users with a specific language. I would use the console, but I need to set a click_action / category and that's not supported in the console (as far as I know).
