Lutron Connected Bulb Remote control Cree bulb connected to ST

I have a Cree Connected bulb that at one time was connected to my ST hub AND connected to a Lutron Connected Bulb Remote, and controllable by both. After moving to the Samsung account and adding my devices back, this no longer works. I really want to achieve this again.

Can anyone suggest how to make the Cree bulb controllable by ST and the Lutron CBR at the same time?

Thank you for your help.
