Lumira dashboard publishing in BI platform

I have Lumira story board based on HANA FHSQL which I had published on  BI platform 4.1 sp4 (Lumira server 1.25)

I need the BI published story board to be accessible via a URL.I managed to do that by opendoc.but I'm facing the below issues

1.Its prompting me for credentials-Is there a way to pass it via opendoc?

2.The story board is not refreshing-Error message is 'refresh is not available in this version'

In the user guide its mentioned as the refresh is supported for FHSQL if based on generic JDBC.but I'm using HANA JDBC for connecting with HANA.

Is there anyway I can connect to HANA with generic JDBC?

Is there anyother way to achieve my requirements?

Thanks in advance
