const AVN_GATEWAY_URL = "<node_url>";
const options = {
    suri: "<account_suri>",
};
const API = new AVN_API(AVN_GATEWAY_URL, options);

const ACCOUNT = "5DAgx...";
const TOKEN_ETHEREUM_ADDRESS = "0x7e5bb...";

async function main() {
    await API.init();

    let token_balance = await API.query.getTokenBalance(ACCOUNT, TOKEN_ETHEREUM_ADDRESS);
    console.log(token_balance);
}

(async () => {
    await main();
