Team Calendar - Google

Does anyone know if you sync a Google calendar to Houzz, can everyone see that and put entries into it or is it just a viewable calendar for whomever owns it? We need a “team” google calendar that isn’t tied to specific projects so that when I schedule customer estimate visits, I know their availability. I believe the schedule with Houzz is tied to projects that that doesn’t help me when I’m trying to schedule appts.
