FCM notification & data objects (v0.11.0)

Hi all! I know that there are a couple of discussions about this subject but I created this one hoping to clear things out a little bit. As I've seen from FCM documentation (v1), while sending a message, one can specify two objects: notification, data. For example:

{
    "message": {
            "token": "device-token",
            "notification": {
                "body" : "Title here",
                "title": "Message body"
            },
            "data": {
                "action": "go_to_link",
                "url": "https://www.novu.com"
            }
        }
}

{
    "message": {
            "token": "device-token",
            "notification": {
                "body" : "Title here",
                "title": "Message body"
            },
            "data": {
                "action": "go_to_link",
                "url": "https://www.novu.com"
            }
        }
}

However, from my testing with Novu so far, when I add the data type in the overrides field, it sends the data but it omits the title&message fields from the template. So, the data fields are sent to the device but the message is empty.. Event trigger example:

{
    "name": "fcm-test",
    "to": {
        "subscriberId": "sera-12345"
    },
    "payload": {
        "title": "Title here",
        "body": "I am the body",
        "action": "go_to_link",
        "url": "https://www.novu.com"
    },
    "overrides": {
        "fcm": {
            "type": "data"
        }
    }
}

{
    "name": "fcm-test",
    "to": {
        "subscriberId": "sera-12345"
    },
    "payload": {
        "title": "Title here",
        "body": "I am the body",
        "action": "go_to_link",
        "url": "https://www.novu.com"
    },
    "overrides": {
        "fcm": {
            "type": "data"
        }
    }
}

I'd appreciate any comments or thought on this 😅 Thanks!

It works exactly as @sheena suggested. Keep in mind that all fields in "data" object need to be strings, even numbers and booleans. For example:

{
    "name": "fcm-test",
    "to": {
        "subscriberId": "sera-12345"
    },
    "payload": {

    },
    "overrides": {
        "fcm": {
            "data": {
                "action": "an_action_to_be_handled_on_device",
                "anIdThatINeed": "9430124",
                "aBooleanThatINeed": "false"
            }
        }
    }
}

{
    "name": "fcm-test",
    "to": {
        "subscriberId": "sera-12345"
    },
    "payload": {

    },
    "overrides": {
        "fcm": {
            "data": {
                "action": "an_action_to_be_handled_on_device",
                "anIdThatINeed": "9430124",
                "aBooleanThatINeed": "false"
            }
        }
    }
}

A big thanks to @sheena for all the help!! 🙂
