Ability to search similar images "from" partner assets

The bug

I am aware of #12614 (Better sharing in Immich)

However, the bug/unimplemented feature is shown as an example below:

accounts: Admin1, User1 sharing: User1 partner shares with Admin1, Admin1 can see User1's photos in timeline photos: Admin1 has p1,p2,p3 photos, while User1 has u1,u2,u3 all of them similar to Admin1's relevant feature: #21108 (Release: https://github.com/immich-app/immich/releases/tag/v1.141.1)

Issue: Admin1 can run similar search on any of p1,p2,p3 AND retrieve u1,u2,u3. However, Admin1 cannot trigger similar search on u1,u2,u3 from the webUI.

p1:

u1:

---

Since Admin1 can see CLIP embeddings of User1, I believe it is no longer a permission issue similar to facial recognition data (i am possibly wrong).

The feature is awesome, could we have a Similar Search in a <button>?
