KNX Operation modes not showing in homekit

Hello.I am installing homekit with knx. But the operation_modes object (preset_mode) in the air conditioner control is controlled via Homeassistant, but I cannot control it via Homekit.
How can I solve it?

Create a Helper toggle, then create an automation that reads the state of that helper toggle (on and off) and if it’s off or on in automation set it to toggle the preset mode accordingly.
