Here are the guidelines for setting up permission sets for your app: 1. **Identify User Roles**: Determine the roles and responsibilities of users interacting with the app. 2. **Assign Permission Sets Based on Access Needs**: For users managing customer orders, assign a standard user permission set (e.g., COA User or CMA Standard User). For users requiring full administrative access, assign an admin permission set (e.g., COA Admin User or CMA Admin User). 3. **Steps to Assign Permission Sets**: Log in to the Salesforce org where the app is installed, go to "Users" in the Setup menu, select the user to assign a permission set, in the "Permission Set Assignments" related list, click "Edit Assignments," choose the appropriate permission set and click "Add," and save the changes. Make sure to assign permission sets only to users who need the specified level of access to maintain security and functionality.
