How to use the @nomiclabs/ethereumjs-vm/dist/state/promisified function in @nomiclabs/ethereumjs-vm

private constructor(
    private readonly _vm: VM,
    localAccounts: Buffer[],
    private readonly _blockGasLimit: BN,
    genesisBlock: Block,
    private readonly _throwOnTransactionFailures: boolean,
    private readonly _throwOnCallFailures: boolean,
    stackTracesOptions?: SolidityTracerOptions
  ) {
    const config = getUserConfigPath();
    this._stateManager = new PStateManager(this._vm.stateManager);
    this._common = this._vm._common as any; // TODO: There's a version mismatch, that's why we cast
    this._initLocalAccounts(localAccounts);

    this._blockHashToTotalDifficulty.set(
      bufferToHex(genesisBlock.hash()),
      this._computeTotalDifficulty(genesisBlock)
    );

    this._getLatestBlock = promisify(
      this._vm.blockchain.getLatestBlock.bind(this._vm.blockchain)
    );

    this._getBlock = promisify(
      this._vm.blockchain.getBlock.bind(this._vm.blockchain)
    );
