For Hubspot, how to "receive instant data updates using webhook"

Could some clarity be provided on this setting in the Hubspot integration?

Even though I have it selected, if I make an update in Hubspot it doesn’t seem to trigger any change to any Hubspot entities in Fibery. Based on the way it’s worded, I assumed that change would be fairly instantaneous.

Is there a certain tier of Hubspot or settings that I need to change to get this “instant data update” to work?
