Show Resource Availability within List Calendar View

Hello all,

We are switching some legacy systems from on-prem SharePoint to M365 and part of this includes a booking system built using a SharePoint List.

One interesting feature that this List has is a Calendar view which allows the user to select a specific "Resource" and see the availability in a Calendar View.

I have found how to create the Resources if we choose this approach in 365, however I cannot find a way of viewing particular resources in a Calendar View - any help would be appreciated.

I have attached a screenshot of the existing Calendar View with the Resources selector shown in Legacy SharePoint.

Thanks, Daniel.
