Utilizing Save-to-disk-h264 with a remote WebRTC stream

[ConcreteCoding250]

So I'm trying to use this software to write data from a remote WebRTC stream from a site called RTSPtoWeb. I've gone through all of the steps to use software, other than the ones for getting the remote description, I'm just adding that manually from the stream. The code runs just fine, it even generates an offer, but it never writes any data to my device. Is there anything I may be doing drastically wrong, is this even possible?
