-contents of file `covid-19-lk-dev-firebase-adminsdk.json` in `/src/main/resources/credentials/` into the new `fcm.json`,
-and add the private key from Firebase Admin SDK.
-- change the value of `firebase.configurations.path` in application.yml to `file:fcm.json` or `file:<absolute path of fcm.json>` 
-  (if the value of `firebase.configurations.path` is not changed, the json file bundled in the jar will be referred)

 - go into the folder where the jar is (eg. `cd target`)
