Using Microsoft Active Directory v2 Spoke in Flow Designer: Add User to Groups Action

[jmiskey]

In a Flow based on a Catalog Item, I am trying to use the "Add User to Groups" action from the "Microsoft Active Directory v2 Spoke".  It requires that I provide the "User Name" and "Group Names", and it says that the Group Names field must be a "array.string type pill":

On my Catalog Item, the fields requested look like this:

The AD Groups variable field is a List Collector, coming from a Custom table that has two fields:

On this Custom table, the "Group Name" field is the Display field, but I believe the "AD Group Codes" are the values that I want.

It will not let me drag the "AD Groups" data pill from the Catalog Item into the "Group Names" field (presumably because it is not an array).  So it appears that I somehow need to create an array-type data pill to drop into this "Group Names" field.  

What is the best way of doing that? 

Should I try to do it in a "Flow Variable"?

Or should I create a variable on my Catalog Item and populate it in a Catalog Client Script?

Either way, I am not sure how to create this as an array-type field so that the "Group Names" action will accept it.

I have the same question, did you get anywhere with this?

I believe I created a Flow Variable of String type, then looping through all my selections, and added them to the string, separated by a comma (so I created a comma-separated string).

I then created a Custom Action to convert that string to an array, and used that array in the action to add them to AD.
