Generate/Extract OOB report in pdf using javascript

Hello,

I am trying to extract the OOB report in CRM 2016 online in the pdf format using javascript. I have referred to few blogs where people have implemented the SSRS report in pdf form.

I am trying to get the ReportSession parameters to generate the pdf report. The following query is for SSRS report.

retrieveEntityReq.send("id=%7B" + reportGuid + "%7D&uniquename=" + Xrm.Page.context.getOrgUniqueName() + "&iscustomreport=true&reportnameonsrs=&reportName=" + reportName + "&isScheduledReport=false&p:parameterNamespecified in ssrs report=" + selectedIds);

What would change in the above query for the OOB report.

Thank you.
