Partition Editor Tutorial

Hello everyone,
Does anyone know a complete and detailed training course for the Cubase score editor? It’s very frustrating, because there are very few resources on this subject (Apart from the user manual but it’s not intuitive at all…) and it’s a tool that seems so practical to use, especially when we have midi tracks available. If anyone is used to using this editor, it would be so great if they could make a live video creating a score from A to Z. There are already existing videos, but it really remains focused on the discovery of the tool, and not on the actual use of the editor.
Thanks for reading me.
