Backup account privilege for kiwicattools. Cisco Firewall

I have a question regarding KiwiCatTools.

We have a Firewall Account on the FW with the Username “Backup” which we suspect to be used to create backups from the Firewall with KiwiCatTools.

The Account does have privilege 15 – the highest possible.

Is it really required to have full admin rights? Or would Read-Only be enough for creating the Backups with KiwiCatTools? Which commands does KiwiCatTools execute?
