Can't access unique identifier for Bixby using code from docs - bixby

Question

To access a unique identifier for Bixby, I'm trying to access the contactId field within the contact library (which is also viv.self I think?). I tried using the code snippet found in the docs here, but I'm getting some errors.
Code Snippet (Source)
text (Name) {
extends (contact.StructuredName)
}
Errors
ERROR: invalid capsule alias contact
ERROR: unknown super-type: contact.contactId
I would ultimately like to do something like this
integer (Identifier) {
extends (contact.ContactId)
}
Would appreciate any help on accessing this data!

I ended up finding another way to get a device identifier from these docs. There's also a sample capsule here.
In your corresponding JavaScript file, access the $vivContext.locale parameter to return the locale information.
module.exports.function = function accessVivContext (dummyInput, $vivContext) {
var result = "Testing Access vivContext..."
// See docs for all the properties of $vivContext
result = $vivContext.userId
return result
}
You would then need to configure your endpoints for this action like below, including making sure that you set up the proper accepted-inputs for your endpoint:
action-endpoint (AccessVivContext) {
accepted-inputs (dummyInput, $vivContext)
local-endpoint ("AccessVivContext.js")
}
