Sync Google calendar with Infusion Soft Calendar

Hello,

Is there a way my Google Calendar appointments are also visible to my team mates in Infusion Soft Calendar. They do have the permission to see my calendar, however it does not show up my google appointments. I am trying to effectively utilise the time so that my team mates dont have to switch tabs and look at my appointments.

Any help would be much appreciated?

Only thing other than a custom coded solution that I can think of is to use Zapier
