Emby Hardware Transcoding

I have Emby added through the official repo by TrueNAS and gave it 5 intel igpus. Do I need to do anything special to get hardware transcoding to work, or does it work out of the box? I subscribed to emby’s monthly plan to try things out but want to be sure, as I have seen mixed things here and there. I am coming from Jellyfin where I had a few issues as well which makes me hesitant.
