Um, no, I haven't heard of that feature. Tidal on the iPad plays on the iPad. Tidal on the Mini plays on the Mini.
You can use a remote virtual desktop software like Real VNC to remotely view and operate the Mini from the iPad. You'll need the app running on the iPad and Desktop version running on the Mini. This is great for all kinds of things, particularly if you're running a Mini "headless"
I don't remotely operate Tidal running on the Mini from my iPad because I use Roon for that.
Roon is an application I suggest you look into. It has a great interface on both the desktop and iPad and will do what you want.
Good luck.
