How to set up a page for a bot in Messenger?

Question

Facebook

Following the documentation, I created a page in FB, and connected the webHook. My bot is working. If you write a message to the page, then the bot responds.
But a few things are not clear to me:

1. How to find a bot in Messenger? Only through the page in FB?
   
2. In the page settings, I can go to the "Messages" section and see all the dialogs with the bot. I do not need it. Can I turn it off somehow?
   

Maybe I don't quite understand how Facebook chatbots work...
