Audit failed crud queries/grants/revokes

Trying to identify which records in the %SYS.Audit table are fails.

Eg, as user "WORKER", I run an attempted a grant, the terminal returns:

SQL> GRANT SELECT ON newschema.patients TO COORDINATOR
[S1000][Iris ODBC][State : S1000][Native Code 112]
[libirisodbc35.so]
[SQLCODE: <-112>:<Access violation>]
[Location: <ServerLoop>]
[%msg: <User WORKER does not have required privileges to grant the privilege(s)>]
[ISQL]ERROR: Could not SQLExecute
 

but the record in the audit table gives

Description: "SQL GRANT Statement"

EventData: "GRANT SELECT ON newschema.patients TO COORDINATOR"

Is there any indication in the audit table that this grant failed?

##############

Separately, I run a select without sufficient permissions

SQL> SELECT * FROM newschema.table2
[S1000][Iris ODBC][State : S1000][Native Code 99]
[libirisodbc35.so]
[SQLCODE: <-99>:<Privilege violation>]
[Location: <Prepare>]
[%msg: <User WORKER is not privileged for the operation>]
[ISQL]ERROR: Could not SQLPrepare

I don't get a record for the attempted query in the audit table at all -  just the surrounding login/logout.

How do I capture failed CRUD in the audit table?

TIA
