Listening to Events (Mainnet) , don't see native NEAR transfer events on socket messages

I am listening to wss://events.near.stream/ws using the following filter

{
"secret": "hnftsss",
"filter": [
    {
        "status": "SUCCESS",
        "event": {
            "standard": "nep141",
            "event": "ft_transfer"
        }
    },
]

}

Why I am not receiving ft_transfer events even when I am transfering native NEAR tokens between my two wallets ?
