Creating a Zap for HubSpot-->CommonRoom

I am trying to create a zap for HubSpot → CommonRoom

I have a Static List in HubSpot. If a contact in the list is update, for example with a new activity, I want to update the contact in CommonRoom

For HubSpot, There is an event for Contact created or updated but it is not specific to the list i want to target. I do not want to create or update any contact apart for the list that i have define

Any help/suggestion is welcome
