MS Bookings Calendars being viewable in Outlook Shared Calendars

The trouble we have is that we are unable to see/share the bookings calendars in the our Outlook calendars with stakeholders & managers. All employees go through O365 to the bookings page and enter the calendar from there to look at it. If we were able to see the MS Bookings page calendar where we usually select shared calendars to view them side by side would be a huge benefit.

Does anyone know if this is at all possible. Or anyone else having this challenge?
