Help me pls with adding Mi purifier to Homekit

I am completely new to Node-Red and I am trying to configure node-red-contrib-mi-air-purifier-3.

I was able to make it control my purifier by clicking the inject nodes.
I was also able to somehow add Homekit node visible in Home app as purifier. When I switch it from the phone, I can see "Active 1" and "Active 0" in Node-Red.

Unfortunately I am not able to understand how to make the connection between the two separately working nodes...How to make the Air Purifier node that works from injects, to be controlled by Homekit...

Thank you in advance.
