How to embed "AVEVA (OSI Soft) - Pi Vision" displays

Question

I am working on a website in which I want to integrate AVEVA (OSI Soft) Pi Vision. Main requirement is to embed the Pi Vision displays in the new website.

I have a user, by which I am able to login on the portal and can view the folders and their displays.

I am following this API documentation which can list folders and the displays: https://docs.aveva.com/bundle/pi-vision-api-reference/page/overview.html

I gave permissions to the user mentioned in the above document: Most PI Vision Display API endpoints require an authenticated user to be passed with the request. The user should belong to the PI Vision Utility Users or PI Vision Admins group on the target PI Vision server.

But when I tried to run the following command in Postman:

curl --ntlm --negotiate -u USERNAME:PASSWORD --location --request GET 'https://piegp.******.com/PIVision/Utility/api/v1/folders' --header 'X-Requested-With: cURL' --header 'Content-Type: application/json'

It is not working and giving following reponse:

I never used NTLM authentication prior. Am I missing something in NTLM or there are some configuration related things which I am missing. Or if there are any other way to embed the Pi Vision display, please help me to find out.

Any suggestions will be helpful.
