Cordova-plugin-fcm can't be found

Hi, i’m trying to implement push notifications in my app using the cordova-plugin-fcm.
Every tutorial i’ve seen explains the same and i’ve followed them, but when i try to use the plugin methods i get the error “Cannot find name ‘FCMPlugin’” like in the image:

Do i have to import a module somewhere? There is nothing specifing how do i use it.

I have the same problem, did you solve it?
