Ultimately what I’d like to create is a view of two participants with one participant vertically above the other, (each at 1920x1080 for a total size of 1920x2160). I don’t want any borders, margins, buttons, logos, etc. A 3rd participant (without video or audio) will observe the conversation using this view and that observer should not appear in the list of participants. It would also be great if I could swap the positions of the 2 video participants. Is this possible with the IFrame API or should I be trying to build something more custom using lib-jisti-meet ?
