AWR in OCI ATP

Has anyone tried generating a AWR report in OCI ATP database , considering we don't have physical host access.
I tried 2 options but had hit a blocker for both, if anyone else came across same, kindly assist.

Option#1 ,

I logged in to ATP sql developer as ADMIN user and executed below query to get a list of available snapshots,

select SNAP_ID,DBID,BEGIN_INTERVAL_TIME,END_INTERVAL_TIME from dba_hist_snapshot where INSTANCE_NUMBER=1 order by SNAP_ID ;

And further executed below query to generate AWR in html format,

SELECT output FROM TABLE
(dbms_workload_repository.awr_report_html(&dbid,&instnum,&beginsnap,&endsnap ));

The only problem with above was that the resulted AWR html report when exported from sql developer does not converts into an easy readable format.

Option#2,

The other approach that I tried is by connecting to ATP database from my local machine but for some reasons the ATP host is not resolvable from my local machine though I have modified sqlnet.ora and tnsnames.ora accordingly.

The benefit of this approach would be that we can just spool the html o/p of above query of AWR repository and can view it easily on our local machine.
