I do not want images cropped in Firefly. Help please!

Hello! I am using Adobe Firefly. I am trying to create graphics that are a complete image. I cannot figure out what prompts to use. I end up getting images that look cropped. I don't want any part of the image cropped or cut-off. I tried prompts like "white margin around image", "complete image", etc., but I cannot make it work. Please see attached photo. Thank you very much!
