How to enable "Expand all" in response samples in the Redoc page provided by FastAPI?

Question

In Redoc, you can open the Response samples using the "Expand all" button:

I want to put this as the default value via custom_openapi(). Here is my code:

def custom_openapi():
    if app.openapi_schema:
        return app.openapi_schema
    openapi_schema = get_openapi(
        title=title,
        version="1.0",
        description=description,
        routes=app.routes,

    )
    app.openapi_schema = openapi_schema
    return app.openapi_schema


openapi_schema = custom_openapi()

How can I set it up?

Redoc supports a expandResponses as one of its configuration options, I'm not familiar with passing the Redoc configuration within FastAPI but setting the value "all", it should show all responses expanded.
