How do I get back the Select Reference feature in Generative Fill?

Thank you for your reply! I know there is a similar feature in workspace, but they are actually different use cases.

For example, in the older version, I want add a lamp with a specific look to this image, I can just pick a reference image and it just output what I want directly. But in the new version, I need to randomly generate tons of lamps and still couldn't get a satisfied one. That really took a lot of efforts to do what older version can do.
