Some streamers are offering channel point redeems which scare the streamer. (For example @Player2_Live, @Scarlett, @DreamYeti, ...)

But these don't work if the streamer reads the redeem message in chat before it plays on their PC.

So, maybe let the streamer set the redeem as "invisible" or "stealth". Either it won't show any message in chat, or the message will be delayed by 10-20 seconds.

Oh, and some streamers do the same, but for a set amount of bits. So e.g. they might want to set 200 bits to only appear to the streamer and to chat after 20 seconds, after their automation has triggered.
