To use your iPhone's Guided Access feature, which is an accessibility tool designed to lock your device to a single app, you first need to enable it. Go to Settings Accessibility Guided Access and turn the toggle on. You can also set a passcode and enable Face ID or Touch ID for easily exiting the mode. Once it's enabled, open the app you want to use and triple-click the side button (on iPhones with Face ID) or the Home button (on other models). This will bring up the Guided Access menu, from which you can tap Start to lock the phone to that single app, preventing anyone from leaving it or accessing other features. To exit, simply triple-click the same button and enter your passcode or use Face ID/Touch ID to end the session.
