Hello community
I have a problem with the SharePoint function "get file content using path".
My goal is once the user completes this form, is that the answers are converted into html and pdf document. The form a question allowing him to submit or not a single or a multiple attachments.

Once the form is submitted, the html and pdf document collects all user responses.
The main purpose of this post is to show the filenames that the user can send in the converted document shown below.

Here is in 2 parts the editing structure with Power Automate, the last diagram of which illustrates the problem I need to solve.
