What is the method Power Platform uses to deploy apps to users?

Sharing the app is the method used in Power Platform to deploy applications to users. This approach allows app creators to specify who can access the application, whether it's individual users, teams, or specific security groups within the organization. By sharing the app, developers can control permissions and access levels, ensuring that only authorized users can utilize the application while maintaining the necessary privacy and security measures.

Other options, while relevant in different contexts, do not represent the primary deployment method for apps in Power Platform. Publishing to the store pertains more to applications that are intended for a broader audience beyond a specific organization. Email invitations can support user engagement but do not serve as a direct method for deploying an app. Creating user groups is more focused on organization and management of users rather than the actual deployment of the apps themselves. Thus, sharing the app stands out as the correct and central method for user access in Power Platform.
