Zoom Rooms joining a Zoom Pro hosted meeting - Conference Room Connector license needed

I have a Pro license hosting a meeting. I have people in a conference room set up with Zoom Rooms equipment joining my meeting.

Do I need to get a Conference Room Connector license for my Pro account so that the Zoom Rooms equipped conference room can join my meeting?  

The Zoom Rooms displays an error message:  "The host of this meeting does not have a Conference Room Connector (CRC) license.  ----  An active CRC license is required to use a SIP/H.323 device to join this meeting.   If your account have an active license, please go to - - -."   (see attached picture)

I planning to resume in-person meeting with hybrid zoom. It turned out the facility I will use is a Zoom Rooms facility. 

It seems a Conference Room Connector license for a Pro account is $49 per month. 

Please clarify.

Thank you!
