protoc-gen-openapi: How do I customize a response header in code=200

 I want customize a response header in code=200 like:
<img width="620" alt="Image" src="https://github.com/user-attachments/assets/f6d8eaa0-9fd0-4fb7-b65a-059db28a7c80" />
At present, it seems that only default can be modified.Is there another way？
