How does hugginface make it possible to embed Space on other web sites?

This may not be the right place to ask this, but I couldn’t find anywhere else to ask it except here sorry.
I want to keep my HuggingFace space private and embed it on other sites.
But that doesn’t seem to be possible, so I want to upload the program outside of HuggingFace so I can embed it on other sites.
How can I do this?
I would be grateful if you could tell me.
Thank you very much.

Ok, but I can pay for that.
For example, is it possible to put it up on AWS and then embed it on another site?
