AC fan speeds not presente in Google Home

Dear all,
this is my first post, hello everybody!!!

I succesfully configured SmartIR and a Broadlink device to control my Toshiba AC. I manually grabbed code for COLD MODE, TEMPERATURE (17-30) and FAN SPEEDS (auto, low, mid-low, mid, mid-high, high).
On Home Assistant everything is ok but if I look on Google Home (that’s perfectly working with all my other devices) I can only switch on/off the AC and change the temperature.
I don’t have any FAN SPEED controls.

Could you help me with that?

Thx!
