Offering the option to set a transparent background when using generative AI

While experimenting with the new generative AI, I asked the AI to generate a flying seagull with a transparent background.  However, it didn't seem to know what I wanted. Often the generated content is not proportional to the rest of the image but when you scale it using the Transform-> Scale tool it scales the entire generative layer so its background no longer matches the scale of the area you selected. If I could ask Photoshop, for example, to generate a gold and black butterfly on a transparent background then it would help me to scale, rotate, or even duplicate the butterfly and place the new item(s) elsewhere around the scene without out-of-context background material.
