Gatling: How to access individual values in session arrays?

I'm new to Gatling and Scala, and would appreciate some advice. Using the following code:

.check(
    regex(""""childClientIds":\["([^]]*)"""")
        .find
        .transform(_.split("""\",\"""").map(_.trim).toSeq)
        .saveAs("ChildClientIDs")
)

I've managed to save a list of IDs to the session variable ChildClientIDs. From the Gatling log:

Session(Dashboard,1,Map(ChildClientIDs -> WrappedArray(ID1, ID2, ID3, etc.

How can I access the individual elements in ChildClientIDs and use them in a request? ${ChildClientIDs} will drop the entire array into the request, as expected. How can I just use the nth element in the array? ${ChildClientIDs}[n] and ${ChildClientIDs[n]} don't do the trick.

I think I've answered my own question.

Per the documentation https://docs.gatling.io/reference/script/core/session/el/, ${ChildClientIDs(n)} is the way to go.

If you don't want to use EL, for whatever reason, you can try this :

session => session("ChildClientIDs").as[Seq[String]].apply(indexOfElement)
