I have a Paypal pro account. Following the videos below from paypal explain what I'm trying to do, except that it does not explain how to create recurring billing profile through this method.

I understand through the API how to manually create a recurring billing profile through the Direct Payment API (Recurring), but this only works for users that don't want to go through paypal (even though technically it is). For the people that choose to pay through paypal, I believe it brings them to express checkout. How do I create an iframe on my page like the layout C examples in those videos except for recurring billing instead of a 1 time payment?
I've read in some documentation somewhere about a BAID (Buyers Agreement ID) that might be necessary but I don't know how I would integrate it in the example code they give in those videos. Any help would be greatly appreciated!
