How to show present privileges on table in IBM DB2 Z/OS with SQL

Question

Is there an SQL way to show the privileges present on a table or view in DB2 Z/OS? I would like to achieve something like this:

select * from sysibm.magic_table where table_name = 'users'

|TABLE_NAME|PRIVILEGE_TYPE|USER_OR_GROUP_NAME|
|     USERS|        INSERT|              ANDI|
|     USERS|        SELECT|            ADMINS|

Is that possible?

This query tells the user / role names in the grantee column and the various assigned rigths in the ...auth columns where Y = right present, G = right present and right to grant it to others.

SELECT
    grantee,
    screator,
    stname,
    tcreator,
    ttname,
    updatecols,
    alterauth,
    deleteauth,
    indexauth,
    insertauth,
    selectauth,
    updateauth
FROM
    SYSIBM.SYSTABAUTH
WHERE
    TTNAME = 'MY_TABLE'
    AND TCREATOR = 'MY_SCHEMA' 

Sample result set:

|GRANTEE  |SCREATOR |STNAME  |TCREATOR |TTNAME  |UPDATECOLS|ALTERAUTH|DELETEAUTH|INDEXAUTH|INSERTAUTH|SELECTAUTH|UPDATEAUTH|
