chatbot not able to answer to livechat

Description:

I have a RASA bot and configured following the documentation.
It works on the #general channel
If I try to use it in the omnichannel-livechat it is not invoked.
It seems that the outer webhook do not listen to queues created with livechat.
I've tryed to configure to listen to all public channel, to all DM with no luck.
Any hints on what to configure because in the rasa logs it is not called once.
Queues comes as "guest-X" and we obviously need also to be able to answer to guests.

Steps to reproduce:

1. register a rasa bot following doc
2. activate omnichannel-livechat
3. use livechat and try to talk to bot, bot ignores even if correctly assigned to chat

Expected behavior:

Bot invoked

Actual behavior:

The bot is not invoked and stays idle, probably due to integration hook not used

Relevant logs:

Start with the RASA integration documentation and the omnichannel-livechat webhook and queue configuration described in the report. Reproduce the issue with a guest livechat queue, then trace whether the integration receives the message; done means the RASA bot is invoked and can answer guest conversations.
