Zoom Room without controller

We are trying to run a zoom room without controller, only managing the zoom room remotely. 
A meeting is created by the host, and participants are joined into the meeting and zoom room is also added into the meeting. Once the participants leave, and the host also leaves the meeting, the zoom room still continues in the meeting. Is there any method or settings to remove zoom room from the meeting once all the participants have left.
Presently I’m doing a zoom room end API call to end the zoom room

I see that the zoom room becomes the host once the other participants leave. Is there anyway to disable this? since the zoom room keeps running? Will turning of the co-host feature remove this
