Thanks for posting here in the Community, @nicola10. Let me help you on how to share your management reports with other QuickBooks Online (QBO) users.
In QBO, you can download, send, and copy your management reports. To share the report with other QBO users, you can send them a copy. I'll show you how:
Go to Management reports, then choose the Action dropdown for one of the reports.
Select Send.
Once the window opens, edit the recipients. Enter the user you want to share the report.
As an option, change the subject line and message before sending.
