I use Firebase Cloud Messaging to send notifications to the clients of my application. Clients can be any of the three supported platforms (ios, android, web).
I want the user to be able to click on the notification to launch the application.
To do this, I must specify click_action in the notification. For ios and android that seem like a simple line. For the Internet, this will be a URL.
How can I send a notification that works for a potentially mixed set of devices?
Do I need to separate devices and send them different messages?
