Create alerts for streamers

Well, I’m trying to create a platform that when you open a chest appears an alert to the streamer, as well as streamloots, but I do not find how to do it, some idea … thanks

Most streaming software supports what is called “browser source”

So you make a webpage that will show your alerts, then streamers include that webpage in their stream software.

Then you just send event triggers to that webpage when an alert needs to run
