        collapse_key: 'your_collapse_key',
        
        notification: {
            title: 'TITLE', 
            body: 'BODY' 
        },
        
        data: { somekey : "someData" }
    };
    
    fcm.send(message).then(response => {
       console.log("Successfully sent with response: ", response);
    })
    .catch(err => { 
    console.log("Something has gone wrong!");
    });

To send push to multiple devices change key in message body "to" to "registration_ids" and pass the array of device token to it

    var message = {
       registration_ids: [], // length must be upto 1000
        collapse_key: 'your_collapse_key',
        
        notification: {
            title: 'TITLE', 
            body: 'BODY' 
        },
        
        data: { somekey : "someData" }
    };
