synchronization – Export google calendar into outlook

I have a Google calendar that I want to sync into Outlook (web application). So I reach Google calendar -> Settings -> Settings for my calendar -> Calendar integration -> Secrets address iCal format.

Once I copied that link I open Outlook -> Add calendar -> Subscribe from web, then I paste that URL.

This works because Google’s events are imported but, if I add a new project in Google this is not reflected on Outlook.

Is there something wrong with this?
