Does facebook use iframe apps?

Question

Facebook

I added an iFrame application to VKontakte easily https://vk.com/app7323845_1202838 I want to add it to facebook, but I don’t know how to do it. I don't even know what they look like. There are a lot of manuals on the Internet, but they do not fit, because they are not relevant. Does Facebook use this type of app at all? If yes, how to add?

Thanks
