How can i filter the Event_Type ? what I want is to get the value of Event_Type which is the MT

this is my current code

        if (cachedData) {
            let cachedDatas = JSON.parse(cachedData);
            for (var data in cachedDatas) {
                var keys = data == 'Event_Type' ? 'R150274705' : data;
                console.log("keys", keys)
                let code = data.filter((val) => {
                    return cachedDatas['Event_Type'] == val.code;
                })
            }
        }

this is the data

{"Event_Type":"MT","Subject":"","startDate":"07/05/2022 11:43 AM","startDateRaw":"2022-05-07T03","description":""}
