If you have any sort of example / demo of how it works would be very helpful. I have a good understanding of retell in general but just haven't come across agent transfers much before and can't find much information / examples of them being used. Would you say agent transfers are production ready or more of a concept to experiment with but still has some drawbacks which would limit it's real world use. And also one other thing, I am planning on using some dynamic variables in the initial prompt which will be filled when the call starts, would it be possible to also fill these dynamic variables for the new transfered agent. Basically I have an n8n flow that checks a spreadsheet and fills in some details on the caller. If I did an agent transfer would the new agent also be able to have those dynamic variables filled. Or would I need to have it call a tool to regather those variables
