How to use the @0x/contract-artifacts.ERC20Proxy function in @0x/contract-artifacts

export async function runMigrationsAsync(
    supportedProvider: SupportedProvider,
    txDefaults: TxData,
): Promise {
    const provider = providerUtils.standardizeOrThrow(supportedProvider);
    const chainId = new BigNumber(await providerUtils.getChainIdAsync(provider));

    // Proxies
    const erc20Proxy = await ERC20ProxyContract.deployFrom0xArtifactAsync(
        artifacts.ERC20Proxy,
        provider,
        txDefaults,
        artifacts,
    );
    const erc721Proxy = await ERC721ProxyContract.deployFrom0xArtifactAsync(
        artifacts.ERC721Proxy,
        provider,
        txDefaults,
        artifacts,
    );

    // ZRX
    const zrxToken = await DummyERC20TokenContract.deployFrom0xArtifactAsync(
        artifacts.DummyERC20Token,
        provider,
        txDefaults,
