How to add multiple file URLs from sharepoint to one Trello card

[fahmifasha]

Hi,

I am new to this community, so I'll just start explaining the scenarios:

Scenario:

When an email with attachment(s) comes, the flow will trigger on creating (stores) the SharePoint file(s) to library > then create a shareable URL link > the URL will be stored in SharePoint item column > after that it will create a Trello card with the same name as the email subject and contains all the file URLs in only one card. 

The problem:
When the email has MULTIPLE attachments, it always creates multiple Trello cards as well (with the different file URL for each card).

The GOAL:

I want all the File URLs to be listed on one card. Or if that is not possible, maybe I can select a specific file URL to be listed on one card.

Current Flow:


Is this even possible?


Note 1: I don't quite understand with array system, but if that makes it possible please enlighten me.
Note 2: Maybe you wondering why the Trello is inside the 'Apply to each' node, this because if I create outside 'apply to each' node, it won't get the SharePoint dynamic content.



Thank you
