how to enable supplemental logging?

(pardon the double posting - I originally posted this in the ATP forum, but I discovered this forum appears to be more active)

how do I enable supplemental logging in an Oracle Cloud database (ATP)?

ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
ORA-01031: insufficient privileges
01031. 00000 -  "insufficient privileges"

I know that Amazon RDS for Oracle provides rdsadmin_util functions for doing some system-type functions like this e.g.

    rdsadmin.rdsadmin_util.alter_supplemental_logging(p_action => 'ADD');
    rdsadmin.rdsadmin_util.set_configuration(name  => 'archivelog retention hours', value => '24');

I am hoping that Oracle Cloud provides something similar, but so far I have been finding nothing.
