How do I Sidecar to an iPad of my family member via wired connection?

I usually use my iPad as a second display to my MacBook Pro via wired Sidecar connection and I can keep it fully charged in the meantime, which is very handy. This has been working great until now when I need to use my wife's iPad as a third display. When I connect her iPad to my Mac, it was recognized in Finder at once, but it doesn't show in the list of available devices in the "Screen Mirroring" panel.

I know her iPad has her Apple ID logged in, which is likely to be the reason. But I wonder if there is a way of bypassing that requirement for my "own" iPad from the Sidecar feature, especially when the Apple ID on the iPad is a family member and can share whatever apps I bought.
