Restrict visibility for a especific catalog item

[MariaVitorS]

Hi, everyone! In ServiceNow, I have a specific catalog item that I need to restrict visibility for. After the ticket is opened, only the Requested For and members of the groups assigned to the tasks will be able to see it, both in the table and in the portal.
Can anyone help me do this without affecting the other catalog items?
