Hi there, I'm working on an iOS integration for livekit, we have most of the critical path of viewing a livestream working. I'm trying to test multiple participants in a room, with video streams, to work on the UI for the many-participant view (a scrolling collectionview) we have made scripts that can invoke the live-kit cli to add participants to the room, however to add many participants quickly starts to balloon livekit api bandwidth usage. Is there a way to mock participants with video (without hitting the network) when using the iOS SDK edit: solved this by using a local room, these pages helped https://docs.livekit.io/getting-started/cli-setup/ https://docs.livekit.io/getting-started/server-setup/
