Terraform get element name from the list

Let's say I have a list of variables similar to the following:

"first" = {
    action = "trigger"
    env    = "prod"
}

I know that I can get the values of action and env variables in the foreach loop using ${each.value["action"]} and ${each.value["env"]}. How would I go around getting the "first" field (name of the element in a list)?

I would appreciate any help on this!

Please understand first how for_each works and what each object [1] is. The for_each meta-argument can work with sets or maps. You are using maps. A map is represented by keys and values. Since you already know how to use values, the way to get a key in a map is with each.key. If your map has more than one key, you can get all of the keys with the built-in keys function [2].
