Remix Feature - How to make it work

I have uploaded photos to the remix tool in photoAI and no matter what I type - nothing changes in the image. I don’t see how to use this. For instance, If I upload a photo of an exterior of a home, and I want to change say the front yard or remove a tree or whatever, nothing ever changes. It’s always the same image. There might be 1 small little change but I don’t understand whats the point. On top of that - the # of the image ie. there is a input where you can enter a photo ID to I am guessing influence the creation of photos - how do you get this ID? I have looked at web dev tools and your URl and do not where the photo IDs are coming from. It would be really nice to get a tutorial on how to best use the remix tools.
