There’s an updated (January 2023) Dynamics 365 Licensing Guide. There are a couple of minor clarifications (see the Change Log on page 62), and the addition of Managed Environments throughout. Managed Environments were generally available in October 2022 (http://bit.ly/3WwzXRr) and enable IT administrators greater visibility and more control of apps and flows in an environment. Of licensing-worthy note is that when Managed Environments is activated in a specific environment, all Power Apps, Power Automate, Power Virtual Agents, and Power Pages usage in that environment requires standalone licenses.
