node-red Firebase send notification

I'm trying to use fcm-push to send a notification to Android. I'm just not sure how to build the flow.

I've successfully made Firebase send a notification to android via the firebase console.

just need an example flow for fcm-push. thanks.

In a node this was usefull. I got other problems so I changed from node-red to nodejs but this did the trick. After this just a post node with the right url. token is an array of tokens.

tokens.forEach(token => {
    msg.payload = {
        "message": {
            "token": token,
            "notification": {
                "title": `${titulo}`,
                "body": `${body}`
            },
            "data": {
                "data": `${data}`
            }
        }
    };
    msg.headers = {
        "Authorization": `Bearer ${authorization}`,
        "Content-Type": "application/json"
    };
    node.send(RED.util.cloneMessage(msg));
});

After much trial and error - I was able to come up with this. I did copy and then modify another example - unfortunately I don't know where the final example came from that I got to work (sorry). Here is one that is working, you can "import" into Node Red. Remember to change the AuthKey to your own.

    [
  {
    "id": "b765ca96.a1ef58",
