Wisej Mobile - push-notifications#android

Hello,
I wanted to test the notifications on an Android device with wisej mobile “test” but it was impossible.
I see that you must use firebase, first if I generate the key from the firebase web I generate a “.json” file with the keys and in the wisej documentation the example is a “.lic” file.
In the example it is also indicated to call the Device.SubscribedNotification method to activate the subscription in the client but there is no such method in the api.
Do you know where I am lost?
Finally, can you tell me how I can control if the device is a device or a web.
I have the same web that I might be interested to open it from the 2 methods, I want to control that if it is NOT “device” for example it doesn’t execute “vibration” because it would report an error. I have tried several things but I have not seen it clear either.
Thanks!
