Prototypes for all devices

Hello! Total noob here. I’m working on learning how to use Figma for an app idea I have. I noticed there’s different types of frames for the device the app will be used on. Does this mean I need to make and resize every single frame for each and every viewable device or can I just copy the frames to those device types and have it flow? I don’t have most of the devices on the list so I can’t try it out. Thank you for the assistance!
