Automation to convert .XLSX file to .CSV, then save to new subfolder.

I am trying to create an automation that runs every time a new file is added to desktop folder "Order Trigger". The automation will convert and export the newly added file to .CSV UTF-8 (file_name & ".csv") and save to a subfolder within "Order Trigger" called "Email Trigger".

Trying to streamline my workflow, but have very outrun my scripting ability. Any help would be greatly appreciated.

Thank you!
