Cannot add automation on shared light

So i’ve set up the Yeelight YILAI YlXD05Yl 480 and I can configure it all the way I’d like to, including automation. I’ve shared the device with another phone, but I cannot add automation on that phone. It seems that it’s missing some permissions for that. How do I fix that?

You can login with the same account from other phone.

So only one account can use the automation on a light? I don’t want to use shared accounts, that defeats the purpose of an personal account.
I want to give the other phone the same access right (or as close to), as my own account.
