Bookings for M365 group

Hi everyone, 

We are looking to get Bookings to a M365 group but just want to check if we need to have a shared mail box in order to use Bookings? 

Is a public sector so, we don't want to have to create around 10 shared mail boxes if is not needed.

We do have a M365 group which uses the Teams, SharePoint and etc. Just really want to check if we can use Bookings with the current M365 we have?

Thanks.
