Change Ownership of Apple Photos Shared LIBRARY

My wife and I have iPads - hers is 10th Generation; mine is 7th. We are both on iOS 18.3.1. My wife is the 'Owner' of a Shared LIBRARY (sic, not ALBUM) and I am the only other participant. We want to swap 'Ownership' so that I become the 'Owner' and she becomes the participant.. We cannot find the options in 'Shared Library' that would enable us to do this (as suggested by Generative AI).

Any and all helpful suggestions are welcomed. Than you
