Issue with Listing Tasks from Planner Premium in Power Automate

Hello,

I have created both Standard Planner and Planner Premium. When using Power Automate to list tasks, it only retrieves tasks from Standard Planner but not from Planner Premium. I tried using the Microsoft Graph API /planner/plans/{planId}/tasks, but it does not return tasks from Planner Premium.

I also checked app permissions in Azure AD and tested the API in Postman and Power Automate, but it still does not work.

These methods have been either too complex or have not given any results. 

Is there any alternative way to list tasks from Planner Premium? Any advice would be greatly appreciated. Thanks
