Shortcuts for 2do?

Objective: shortcuts to display one particular Checklist/Project/Task in 2Do.
Problem: only able to display a particular “List” which is one hierachy level above.
Tried: search on forum and 2Do url-schemes page but to no avail.
Expected: either a native Shortcuts 2Do action or url-scheme will do.

When I fiddled around Shortcuts App, there is one native action from 2Do which displays a past checklist, don’t even remember how I got it, nor can I generate new similar actions with other checklist. Is this one of the Siri tricks that I must use this Checklist so many times until Siri automatically recognizes and magically suggests as an action?
