FCM push notification icon: any way to automate this process?

Hello friends.

I am using FCM push notification and it is showing my predefined icon correctly on Android. However, I am not quite comfortable because I had to add my “push icon” manually in “android/res” folder. It means, if I have to remove android platform (and add that again), I gonna lose those icons.

I am wondering if is there an automated way to handle this? (using CLI would be great as we do for “app icon” and splash).
