Hi there everyone!

I am following the example found here → Server API for plugins | Strapi Documentation to create a custom content-type for my plugin but it doesn’t appear in Content Manager nor in the Content-type Builder.

The only change I did was in the file ./src/plugins/my-plugin/server/content-types/content-type-a.js, in the pluginOptions object, I changed both lines from visible: false to visible: true because I actually want to see this content type in the admin.

Also I noted nothing was added in my database also.

What am I missing?

Thanks in advance,
Andreas
