MacOS calendars not visible on iOS

Hi,

I added the same Google account on both MacOS and iOS. I can see all my standard calendars just fine, but on MacOS, I can also see "delegates" under "Accounts > Delegation > Accounts I can access". These are calendars that are used by different groups and are shared with me.

On iOS, I can only see my standard calendars and not the "delegates"/shared ones, even though other calendar apps do show them. How do I get the shared calendars on iOS as well?

iOS 18.6

MacOS 15.3.2

Thanks in advance!
