I would like to apply the [Configure back button] of my personal bot.

Min-Kyu_Jo - You can add the code to handle the back button action in the component or page where you want the back button to be displayed. Typically, you would add this code in the component that represents the view where the back button should be available.

Implement the logic to handle the back button click event. This logic should navigate the user back to the previous page or view within your app.

Sample code ref: https://github.com/OfficeDev/Microsoft-Teams-Samples/blob/40cbc1dc61728d997c2d138dece5053fa5072041/samples/tab-app-navigation/nodejs/src/components/tabOne.tsx#L59

Thanks, 

Prasad Das
