Does the "in" operator work in the playground? I'm trying to write a parallel example to

condition:
  match:
    any:
      of:
        - expr: R.attr.status == "PENDING_APPROVAL"
        - expr: "GB" in R.attr.geographies
        - expr: P.attr.geography == "GB"

like this:

condition:
          match:
              expr: "name" in request.resource.attr

but just getting

If you change your rule to break onto a new line it will work

                  expr: >
                    "name" in request.resource.attr

ooo there we go!
