Setting up Zoom with Outlook

Hello,
There is a task in conjunction with Zoom and Outlook (Exchange)
when assigning a meeting, choose Zoom as the venue
when scheduling a meeting, it needs to have a possibility to check if zoom is free at a given time
ideally, outlook should not allow it to make an appointment for a time that is already taken (needed for different time zones)
The meeting invitation should include a zoom link

Will I need to purchase a subscription to Zoom Rooms or will I be able to do without a subscription?

Thanks in advance.
