PI and Resolve 18: How do I set text as an emitter?

I’m in Resolve 18 and trying to figure out how to use text as an emitter (I’d like to have my text “on fire” or blow away like dust). I found John Dickinson’s video on the latter, but he’s in AE and it didn’t seem to work in Resolve.

What didn’t work? As long as the layer has transparency and you use the “get alpha from layer” option as shown in the video it should work fine. Did you use the same emitter as John did?
