Hey
@clean-jordan-46679, any particular reason why you're using v12? The cloud version is
much easier to work with.
To answer your questions:
1. To make a choice skill that can take button or free text input, you need to set the number of retries to 0 and add an
on fail transition that goes to another node where you listen for intents. If you want to listen for qnas instead, you'll need to manually send the qna with an action like
https://github.com/botpress/solutions/tree/master/custom%20solutions/Send%20Specific%20QnA%20to%20a%20User
2. There are no knowledge bases in v12, only qnas. You cannot upload a document or search a website, only manually add questions and answers. For best results, we recommend 15 - 20 utterances per qna.
