ORA-01031: insufficient privileges not audited

Hi,
We have Oracle 19.12 running on Oracle Linux 7.
I am trying to find out why 'insufficient privileges' is not showing.
I am auditing 'audit insert any table'  The failure is not shown when I query 'DBA_COMMON_AUDIT_TRAIL '

My current settings:

SYS@DPPROD1> show parameters audit

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

audit_file_dest                      string      /u01/app/oracle/admin/DPPROD1/

                                                 adump

audit_sys_operations                 boolean     FALSE

audit_syslog_level                   string

Thanks,
