Does anyone know how to create plugins with YeoMan? The manual at https://www.tiny.cloud/docs/tinymce/6/yeoman-generator/ does not say anything specific, and the yarn build command itself does not work because even this command is not defined "(Command" build "not found .) Does anyone know how to do all this with YeoMan?

EDIT 1

Ok, I managed to get everything up and running after many hours.
