How to make Power App and Power Automate work together?

Power Platform - General

The author was working with Power Apps and the Microsoft Graph API to interact with it asynchronously.
The process involved creating a Power Automate flow to interact with the API details and building a Power App with fields and a button to trigger the flow.
The goal was to enter an email address, retrieve data from the Graph API through the flow, and display the data in a text box.
The Power Automate flow used the Power Apps (v2) connector and a trigger for when Power Apps calls a flow to pass parameters.
Despite getting the flow and button in Power Automate working, the text display in Power Apps was not functioning as expected.
The author realized they missed adding a "Respond to Power Apps" block at the end of the flow, which caused the issue.
To resolve the problem, the author simply refreshed the flow in Power Apps to adjust its expectations for returned parameters.
The order in which the Power Automate flow was added to the Power App was crucial for Power Apps to determine the expected return values during runtime.
