This is a club welcome sign!
It has a particle sparkle and a triggered particle effect!
There are a few ways to trigger the effect, just understand which ever one you use first. is the only one that will work thereon in that chat session.
I suggest when you load the room you say what ever one you want to use straight away
Trigger words are: hi, or welcome, or hello or greetings
