How do I add an analytics label to data messages with the Javascript (or typescript) Firebase Admin SDK?

Question

I want set a label in the message.And I read the official document here and similar question here.

But I can't figure out how to write it in javascript.

my code here:

const message = {
    notification: {
        title: "myTitle",
        body: "myBody"
    },
    condition: "!('TopicA' in topics)",
    AnalyticsLabel : "mylabel"             <=== something like this?
};
const response = await admin.messaging().send(message);

    fcmOptions: {

    }
};
