No "Add Siri Shortcuts" button on Shared Account's App

Hi, I shared my Yeelight devices with my wife’s account and we both use iphones and Yeelight apps. The issue is on my app I can see “Add Siri Shortcuts” button but on my wife’s app there are only “Feedback”, “Device” and “Add to Home” buttons. Besides, there are no “Name” and “Share Device” buttons but I can see them on my app. Yes, she can control my devices by touching buttons on her app but why she is not to add Siri shortcuts? Please help me, what to do?
