Documents attachments available on the Web

Good day

Attachments that are sent with the invoices are somehow showing on the web.

Assistance is sought.

Thank you in advance.

Could you please specify this situation?
I can’t imagine how Google should get any links to attachments from your InvoicePlane setup and indexing should be prohibited due to the robots.txt that ships with every package.
