SQLite - how to connect to Slingshot?

Hi Everyone 

This might be an easy one for someone - I'm just a little bit new to this.

Just wondering if someone could provide some guidance on how to set up Slingshot to work with SQLite?

The 'connection settings' in the 'Connection String' Component does not provide an option to connect to SQLite.  Is there something I need to do to set this up?  (see pic below)

I'm running: 

SQLite Version 3.23.1 (see pic below)

I Have the latest version of Slingshot downloaded from here...

https://provingground.io/tools/slingshot/

(which I assume has SQLite Connection capabilities?)

and running:

Grasshopper Version 0.9.00.76

Thanks in advance for your help! :-)

p.s. the end goal if you're interested is I would like to use slingshot to access to a large spatialite database file from OSM...as an alternative to using elk or other GIS components which struggle to process large osm files.
