Based on the input I received in this post, I built two feedback skills based on the demo bot mentioned here. I linked my skills to the ask-feedback skill and the ask-feedback to the save-feedback skill. Unfortunately, nothing happens. I'd be happy to share my bot so that we can have a look at it together.
I should have included the customer satisfaction skill when creating the bot and it seems it's not possible to add the skill afterwards.
Thanks and best regards,
