### Issue

Hello,

I wanted to know if it's possible to use this plugin when using `fastify-cli`, because the starter point of the application (i.e., `app.js`) is a plugin in this case, how would one go to use it along with this module?

If it's indeed possible to use this plugin along with `fastify-cli`, a minimal example would be helpful.

Thanks,
