Bulk File Search Using Purview (Data Deletion Request)?

Hello,

Our organization is looking for a solution to discover ~13,000 file names (in a CSV) across our M365 environment. Obviously, we are looking for a solution using PowerShell and possibly the Graph API since this is not possible using the Purview GUI. 

Any recommendations on how to do this? We have approached Microsoft regarding this and they provided a Copilot generated PowerShell script as a launching off point but we have not gotten this to work yet. 

Best regards,

Luke F.
