apoc.dv.queryAndLink how to specify direction?

[florin-singuran]

Hello,
I am using https://neo4j.com/labs/apoc/5/virtual-resource/ and trying to use https://neo4j.com/labs/apoc/5/overview/apoc.dv/apoc.dv.queryAndLink/ to load db nodes and link them to the parent node but I can only create outgoing relations.

MATCH (c:N1 {id: 29})<-[*0..]-(cp:N2)
CALL apoc.dv.queryAndLink(c,"RELATION", "db_declared_function",{ id: cp.id }) YIELD path
RETURN path

I couldn't find any info on this, I tried
apoc.dv.queryAndLink(c,"RELATION", "db_declared_function",{ id: cp.id }, {create:true, direction:"IN/OUT"})
as I've seen for other functions but it doesn't seem to work.
Any help would be greatly appreciated.
On the same note, what values go in the config map?
Thanks!
