Strapi v4.9.0 cannot create custom Plugin - not shown in Admin Panel Side Bar

Hi, i also used typescript. But the suggestion from the previous comment also did not help me. In the end I did have to re-build the project but my project was contained in a docker container. So, if you work with docker you will have to ‘npm run build’ in the container, not just at the root of your project. If that is the case, I can, if you want, send you the comment to get into the container.

Cheers
