Deployment/DeployPowerPlatformClient.md:238

• [nitpick] Consider capitalizing and clarifying the product name for consistency, e.g., 'The Copilot control in the Power Apps Canvas App is currently non-functional...' to match style with other headings.

The Copilot control in canvas app is currently non-functional and included for future use. It will be activated once support for the required data source becomes available.
