Siri extension messages

Hi

I'm working on an Siri extension for a test app.

So far I have build an extension to my app, linked

all targets in an app group and build my app to authorized

to use siri.

but everytime I try to test it with Siri I get the response, that my app

isn't set up to work with Siri.

Any ideas or advice would be geat thanks in advance
