How to make siri ask user for inputs programmatically.

I dont know if this is the appropriate forum for this.

Answers I've found on the web points me towards intentions, but somehow I couldnt make it work.

Im trying to activate siri on carplay to ask user for voice input then make a search.

Is this a custom intent capability or is there any other way.
