First time setup webhook. How to subscribe to `message` in the webhook setting?

Question

I would like to have a log chat on my own server by collecting them from the chat history between user and my Facebook page.

I found the document mention about message

Next after I can verify my token using ngrok get my server connected with Facebook. Then I am looking for message.

In my understanding I have to listen to my page event. But I could not found and row mentions about it.

I found message_sends in the User. But it is not what I want.

I think document might not get uptodate. In the picture it is 2 and now it is 3.

Obviously subscription to User and select message_sends is not a correct solution on my use case. My case is user send message to my page. And my page send webhook to my chatlog server. That's all.
