Convert plugin spotlight camera to hardwire

I’m trying to find instructions to convert a “plugin” spotlight camera to a hardwired configuration.   The available Ring hardwired kits I’ve found only address “hardwired” or “battery” versions of the spotlight camera.   Does anyone know of a kit for this specific type of conversion?    I’m thinking that if no “kit” exists, I would cut the plugin cord and pass through a hole drilled in the mounting cover; expose cut ends of wire and connect to house wires with wire nuts; seal drill hole with silicone.   Any recommendations would be appreciated.  Thanks
