This is to make it easier to add new arguments to the method in the future. We will remove the already existing method accordingly to WebRTCs deprecation rules. Bug: webrtc:358039777 Change-Id: Id0706de5216fbd0182cac80ebfccfc4a6a055ee8 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/364642 Commit-Queue: Fanny Linderborg <linderborg@webrtc.org> Reviewed-by: Erik Språng <sprang@webrtc.org> Auto-Submit: Fanny Linderborg <linderborg@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43181}
