How to add external mongo db in backendless pro?

I have installed Backendless Pro in Ubuntu following these steps https://github.com/Backendless/BackendlessPro/blob/master/README.md

Now I want to connect to external mongo DB, I read about External Data Hosts https://backendless.com/documentation/backendlesspro/st_external_mariadb.htm, but not able to get to /apps/backendless/htdocs/conf/backendless.config

Hi Rohan,

At the present moment we support the following external databases in Backendless Pro:

  • MySQL
  • Postresql
  • SQLite
  • Oracle
  • SQL Server

MongoDB cannot be currently added as an external database. To add a database you need to select the Data section in Backendless Console, click the drop-down which says “Backendless Database” and then select the “Add Connection…” menu:
Monosnap%202018-12-03%2012-09-49

After that, you can select the type of the database connection you need to create:

Regards,
Mark
