Client Extension - when is query called?

Hi, I am developing a client extension and want to filter data after i have used my query. I.e. I could do the following:

$allModels: { 
  findUnique({args, query}){
    return query({...args, foo: "bar"}).then((queryResults)=> queryResults.filter((x)=>x))
  }

$allModels: { 
  findUnique({args, query}){
    return query({...args, foo: "bar"}).then((queryResults)=> queryResults.filter((x)=>x))
  }

Is this legit? I am wondering, because client extensions can be chained. So the next extension would get the args and query, but they would not fire, right?

Hey, I believe this should work. But, I would need to reproduce this to confirm. Have you looked at these examples, some of the usecases are similar to what you want to achieve: https://github.com/prisma/prisma-client-extensions/tree/main
