setVariable with object

First question,
Ex:
const myObject = {
identity: 'primary',
text: 'ABC'
}
survey.setVariable('someObject', myObject)
And I access to that variable in survey json
visibleIf: "{someObject.identity} == primary"
It didn't work.
Do we support that?

Second question,
I use https://restcountries.eu/rest/v2/all
That response a property languages, it's an array, with elements are objects.
And I want to assign valueName with element in that array that have "name": Pashto.
Can we do that?
Because I see that we can assign valueName something like: languages.0.name.
With that zero params, can we use some syntax like Jsonpath or xpath like languages.[name=='Pashto'].name?
Sorry if It's difficult to understand.
