Just curious: 1) which country/eID is this? and 2) does it send the date of birth back, or does it perform a zero-knowledge proof that the date of birth is greater or equal than a given value (current date minus age requirement)?

A handful of states, including California, have a digital ID that can do this. It only sends the fact that you’re over a certain age.

There’s a video halfway down this page showing the process in Apple Wallet: https://learn.wallet.apple/id/ (notice “Age Over 21”)
