To allow others to use a canvas app, the creator must explicitly share it with them. The sharing feature in Power Apps is the primary mechanism for granting permissions to other users or security groups within an organization. When sharing, the creator can assign the 'User' role, which allows coworkers to run the app but not edit it. This process also ensures that permissions for any underlying data connections, such as those to SharePoint or Dataverse, are appropriately handled so the app functions correctly for the end-users.

B. Send the URL for the app to coworkers. Sending a URL only provides the location of the app; it does not grant the necessary permissions to access or run it.
C. Add a license for the app. Licenses are assigned to users by an administrator, not to individual apps by the creator. Users need a license, but this is not the action the app maker takes to grant access.
D. Create a Flow for the app. Creating a Power Automate flow adds automation and functionality to an app but is unrelated to managing user access permissions.

1. Microsoft Learn, Power Platform Documentation. "Share a canvas app in Power Apps." Under the "Share an app" section, it states: "After you create a canvas app that addresses a business need, specify which users in your organization can run the app and who can modify and even reshare it. You specify each user by name, or you can specify a security group in Microsoft Entra ID." This directly confirms sharing is the required action.

2. Microsoft Learn, PL-900 Learning Path. "Create a canvas app in Power Apps." In the "Share an app" unit, the first paragraph reads: "Now that you have a fully functional app, the final step is to share it with the users who will be running the app." This aligns with the core requirement of the question.

3. Microsoft Learn, Power Platform Licensing Guide. "Overview of licensing for Microsoft Power Platform." The document details how licenses are assigned to users to grant them rights to use Power Platform services. It clarifies that licensing is a user-centric concept, managed at the tenant level, not an app-specific setting controlled by the maker. See the "Power Apps and Power Automate use rights included with Microsoft 365 licenses" section for examples of user-based licensing.
