You can take screenshots of the Preview module of your iOS and Android apps from your respective preview sections. Go to App Preview and click on the iOS or Android emulator to run a live preview of the app. When the screen that you want the screen shot for appears, go to the section above the app layout and click on the screenshot icon. As soon as you click here, an image file of that screenshot will be downloaded in png format and saved to your device. Repeat this step and take multiple screenshots of different sections and screens of the app as required. If needed, you can also click on the replay icon to restart the preview at any time.
