In order to synchronise a Google meeting room calendar availability to Worka, two things need to be configured in Worka Team:
Set up "account integration" for Google
Map Workplace meeting room to existing meeting room definition
After you have set up account integration, a new calendar source will be available in the floorplans editor when adding or modifying meeting rooms.
This source will allow you to choose additional choices for managing a room availability between 'Microsoft 365' and 'Google' (depending on your integration settings).
For Google, you will need to enter the ID of the meeting room you want to synchronise availability with. This can be located via the Google meeting room sharing options.
