Trouble Locating Build Output for Custom Plugin and Registering It

I have created a custom plugin following the develop the first plugin guide , and it is working fine in my local environment. I now want to move the plugin to my production server.

I have followed below steps to create the plugin-
yarn build @nocobase/base yarn build @example/plugin-test

I did not encounter any errors during the build process. However, I cannot find the build output anywhere. I checked the storage directory in the project root and all directories within the plugin root directory, but I am unable to locate it.

Where can I find the plugin build? Additionally, what is the recommended way to create the plugin build and register it in a registry?
