Technical requirements
To get started, we recommend that you use a demo or development environment, which will give you more power to configure and test some of the features and tips that will be presented in the topics.
If you still don't have a Microsoft 365 account or an environment for your tests and development, we recommend that you create an account using the Microsoft Power Apps Community Plan, as it's free for personal use and Microsoft provides a place where you can explore and try out all the features (including the premium ones). These test and development environments, as well as the trial licenses that can be claimed, have a limited period of use.
