No need to wait, just go this way - I have tested it today for ZH and works fine with IBKR. This solution is open source and free of charge. No need for 3rd parties to access your IBKR account.
If you find any issues, just report them in the linked thread or even at GitHub. There were quite some improvements done in the past few days.
