BO4 - Delete privilge and other user reports in anothe users folder

Hi,

Considering granting the delete privilege via an acess level to a limited number of users.

Whilts can set the Delete objects that the user owns right to granted want  to makes sure that user can only ever delete theor own documents.

e.g if they create a folder but other users put their eports in that folder want to esnure the user with delete priivilege can only delelet their repots and not the folder and its entire contents since they are the owner of th efolder but not all reports in that folder.

What is best practice to achieve this?

Thanks
