If you go to the debug tab in the sidebar you can copy the path to an object property with the first of the three icons that are next to it
Than you can use this copied path in a change node

Your payload is a json string representation of a javascript object than. Simply feed it through the json node from the palette first and it will be parsed to a nice javascript object where you can use the above method.
Where is that value coming from? If its from an mqtt node you can actually select in the mqtt in node to parse the value and emit it already transformed to a nice workable js object.
