Share External Library - proper way

Tried google and found some solutions from a year ago, but I read on Immich site it is in rapid development so what is the PROPER way to let family see the face tagged photo library I added to immich?

1) 1 email/user is not safe

2) Read that if I add my external photo library to another user, they will loose tagged faces and I'm sure they won't be able to use this nice feature.
