My client is planning to implement Power Apps and Power Automate on SharePoint Server 2016 Feature Pack 2. I am aware that we will need on-premise data gateway to integrate Power Apps and Power Automate to on-premises SharePoint list. I am not sure about the licenses. What subscription do we need to purchase that make Power Apps and Power Automate work. Please note the forms and workflows planned to develop in both Apps will be used by entire organisation.
