Deploying is one line of registration.

Add the extension to the exported extensions array in `extensions/index.ts`. The extensions server picks
it up automatically from there.

When custom actions don't appear in Studio after a deploy, check this registration first: an extension
that builds fine but isn't exported is invisible rather than broken.

When you merge a PR from the extension repo, it's picked up by the Awell builder server and deployed to Sandbox automatically. It’s important changes are backwards-compatible. When ready, reach out to the Awell Team to bump your changes to production.
