Cannot use proposed capability - AirPurifierFanMode in AirPurifier device

I can’t define my AirPurifier device in Device Profile (ST developer workspace) because I can’t see airPurifierFanMode capability on dropdown list. I found the capability in Proposed Capabilities - Proposed Capabilities | Developer Documentation | SmartThings. But some of them are available.

Can you help?
