Bitrix24 Bot API, how to properly receive events via webhooks?

Question

Bitrix24

We need a chatbot in Bitrix that connects to the API on node.js. I use ngrok for debugging.
Through the incoming webhook, I call the imbot.register method with the following parameters:

{
    CODE: 'mynewbot',
    TYPE: 'B',
    EVENT_MESSAGE_ADD: 'https://xxxx.ngrok.io/bxchatbot',
    EVENT_WELCOME_MESSAGE: 'https://xxxx.ngrok.io/bxchatbot',
    EVENT_BOT_DELETE: 'https://xxxx.ngrok.io/bxchatbot',
    OPENLINE: 'N',
    CLIENT_ID: 'mynewbot',
    PROPERTIES: {
        NAME: 'Борис',
        LAST_NAME: '',
        COLOR: 'GRAPHITE',
        EMAIL: '[email protected]'
    }
 }

The bot ID is returned in response.
When sending a message to a bot in Bitrix, the request does not come.
Tried using outgoing webhook, changing TYPE and CLIENT_ID, still doesn't work.
Question - is it possible to make a bot through webhooks and what am I doing wrong for this? Or try using oauth?
