advertising: {
                client: "vast",
                schedule: {
                    "myAds": {
                        "offset":300,

You can add 2 VAST ads by using the schedule block:

advertising: {
                client: "vast",
                schedule: [{
                        "offset":300,
                        "tag": "https://www.example.com"
                    }, {
                        "offset":600,
                        "tag": "https://www.example.com"
                    }]
            },
