Quick Answer
The correct answer is the command bar designer in the app designer. This tool is the modern, built-in Microsoft interface for adding a custom ribbon button to a model-driven app, and it directly supports configuring that button to run a Power Automate flow without requiring custom code. On the PL-900 exam, this question tests your understanding of low-code customization options versus developer tools—a common trap is choosing the Ribbon Workbench (a legacy third-party tool) or the Solution Explorer (used for classic, not modern, ribbon edits). Remember that for simple button actions tied to flows, you stay inside the app designer’s command bar, not the component framework or external tools. A helpful memory tip: “Command bar in the app designer commands the flow” — keeping you focused on the official, no-code path for ribbon customization.
