Gitlab node api

Rae there is plans to add more examples on how to use Gitlab API wrapped in the following package

The package page has a link at the general api docs

however .md files don’t explain in details how to use actual node api but rather SOME details of the api request per subject.

so for example

doesn’t explain what project attributes can used in as part of “search” parameters to limit the selection.

here is mo direct question: how the one can select projects for specified “parent_id” or “path_with_namespace” to let’s say select all projects in a given group/subgroup

Thank you in advance
