Get chat history with Whatsapp Lite integration

Hello. I am trying to get the chat messages with a given chat_id in the URL:

https://amojo.kommo.com/v2/origin/custom/{INTEGRATION_ID}/chats/{chat_id}/history

But i always get a 404, don't matter what i pass in INTEGRATION_ID and chat_id.

Reading the API documentation for the Chat API: https://developers.kommo.com/reference/register-channel#/
I got confused with this first step. So i can't use an already made integration (like Whatsapp Lite) in order to get the chat history or send messages?
