Yes @Tai Vu I got your point. But I am writing a script in Python to fetch users who have read access to a specific table. I fetch the roles of users and compare the above roles. But when I set sys_security_acl.operation to read I got ml_report_user and ml_admin. which breaks my script as the user only has ml_report_user or ml_admin role and does not read the incident table. Do you have any other way to find this,
