Hello, I’m trying to get some historical data but get a “not found error” 404 while using the websocket:

```auto
body = {
        "symbol": "ESM4",
        "chartDescription": {
            "underlyingType": "Tick",
            "elementSize": 1,
            "elementSizeUnit": "UnderlyingUnits"
        },
        "timeRange": {
            "asMuchAsElements": 200
        }
    }

endpoint = 'md/getChart'
_request_id = 1

ws.send(f"{endpoint}\n{_request_id}\n\n{body}")

```

error message : {‘s’: 404, ‘i’: 1, ‘d’: ‘“Not found: md/getChart”’}

Could you please help figure out how to get historical data? and also I where I can find all the field mapping to get in the body for different endpoints ? checking the documentation I don’t see much information on this part.
