---------------------- Hmm, I don't know enough to give you a confident answer yet. The knowledge sources provided do not contain specific information on how to modify the or to default to the "create" page of a resource in Ant Design 5 with Refine.
However, you can customize the component using its props or with the swizzle feature as mentioned in the documentation(https://refine.dev/docs/ui-integrations/ant-design/components/themed-layout#sider). You might be able to achieve your goal by customizing the component to include a link that directs to the "create" page of your resource.
For more detailed guidance, I recommend checking the Refine documentation(https://refine.dev/docs) or reaching out to the Refine community for support. ---------------------- Note: you can ask me a follow up question by @ mentioning me again ----------------------
