What to do after agency RFP matched?

I just turned my Bubble account into a Bubble agency account and gave RFPs. I got matched with a client but don’t know what to do now.

I have access to client’s email and we are going to start working. How to make the offer move from “Matched” to “Won” tab?

Is the payment going to be made over Bubble - like Upwork - or is it going to be over a traditional company to company transaction. If it is over Bubble is there a service fee?
