Download impossible despite IRM

Hello,
I understand the major goal here is to prevent files from being downloaded, IRM may not be for that sole purpose but rather as a SharePoint or Global admin there is a new feature you can deploy to block download of files from SharePoint sites or OneDrive without conditional access policies. This can be set for individual sites and also from organizational level.
Kindly follow the below steps to test or setup this policy.

1. Download the latest version of PowerShell using this link https://go.microsoft.com/fwlink/p/?LinkId=2552512. Connect to SharePoint as a Global Administrator or SharePoint Administrator by running the command Connect-SPOService -Url https://contoso-admin.sharepoint.com3. Run the following command, Set-SPOSite -Identity <SiteURL> -BlockDownloadPolicy $true For example, Set-SPOSite -Identity https://contoso.sharepoint.com/sites/research4.In any case you have some users or groups you would like to exempt from the policy so they can still download on the site, you can include this parameter -ExcludeBlockDownloadPolicy in the script. For Example, the parameter -ExcludeBlockDownloadPolicySiteOwners $true will allow Site Owners group download from the site regardless of the policy.

For more information on this feature which may be very helpful, you can look up the Microsoft documentation https://learn.microsoft.com/en-us/sharepoint/block-download-from-sitesFeel free to let me know if this helps.
