If you were using an extension you wouldn’t need a chat command…
Chat commands would work for compiling the result into a poll via chat spam.
With an extension this would either render over the video as a poll ,or in a panel below the stream as a poll. The panel would probably work better as it has better mobile support.
In the interim you can use any poll extension that already exists. But it could be optimised to do a R6 specific poll (using relevant imagery). I can stick it on my maybe todo list, but it’s gonna stack behind paid work
