You have a Teams deployment. You need to customize the message that is displayed when a user requests access to a blocked app. What should you do in the Microsoft Teams admin center?

Creating an app setup policy controls app availability and pinning for users, but it does not customize the message for blocked app requests.

Configuring Notifications and feeds settings under Teams settings relates to user notifications within Teams, not custom messages for blocked app requests.

Creating a policy package bundles multiple policies for easier assignment but is not the specific setting to customize the message for blocked app requests.

"Customize app store settings" refers to branding the Teams app store, not customizing the message displayed when an app is blocked.

The "Org-wide app settings" within the "Manage apps" section of the Microsoft Teams admin center includes an option to customize the message shown to users when they attempt to access an app blocked by an administrator. This setting allows organizations to provide specific guidance or contact information.
