Dialogflow Retrieving Start Page, End Session Page via API call

[sonhj07]

Hi I tried to get Start Page/End Session pages provided from Dialogflow CX as default pages.

However I was not able to get those pages in API level which leads me not being able to implement test cases along with those pages.

The image above shows one of my flows

when I trigger list_page API, it just returns the custom pages in blue box but it does not return default pages such as End Session or Start Page in API level.

# Initialize request argument(s)
request = dialogflowcx_v3.ListPagesRequest(
    parent=parent,
)

# Make the request
page_result = client.list_pages(request=request)

Could you please help?
