How to parser a raw_payload - http device

Hello guys, I would like to parser my raw_payload below. I have a really difficulty with javascript and I couldn't do the parser correctly. Could someone help me?

The property "payload" is the data from a tractor and the others are the data from which the device uploaded the data.

{
    "feature_id": "NVX_FE_tracking_version_01",
    "feu_id": "dad95659-f325-4b81-a61c-809cd63b074c",
    "organization_id": "96WED6",
    "type": "featureMessage",
    "payload": "{\"type\": \"location\", \"payload\":{\"latitude\": -21.478800, \"longitude\": -47.323620, \"timestamp\":1666295981, \"data\":{\"oil\":0,\"fuelRate\":0,\"rpm\":600,\"speed\":0}}}"
}
