Since this is a Kotlin snippet, we might want to demonstrate KTX here
Suggested change

This can be simplified to:
Suggested change
| val tokenMap: MutableMap<String, String?> = | |
| HashMap() | |
| tokenMap["fcm_token"] = token | |
| val tokenMap: MutableMap<String, String?> = hashMapOf("fcm_token" to token) |
| tokenMap["fcm_token"] = token | ||

| // Send token to backend server | ||
| val callable = FirebaseFunctions.getInstance().getHttpsCallable("updateToken") |

Maybe we can demonstrate KTX here too:
Suggested change
| val callable = FirebaseFunctions.getInstance().getHttpsCallable("updateToken") | |
| val callable = Firebase.functions.getHttpsCallable("updateToken") |

If the comment above gets applied, we'll need to import functions ktx.

Developers should regularly send their FCM registration token to their corresponding server. This way the server can determine the freshness or staleness of a particular token and decide whether or not to send messages to that token.
This snippet demonstrates sending the FCM registration token to a callable function that will store it appropriately.
