Registering custom components in Plasmic.

Plasmic Studio Questions
1

I’d like to use custom components in Plasmic. I’m using Codegen, and the Plasmic documentation says that I should register the components in plasmic-host.tsx. That file doesn’t exist - is this just a convention, and can I do the registrations anywhere before is rendered?
