Mongodb更新特定元素的数组元素

Question

我在MongoDB中有一个文档

{
    "_id" : ObjectId("5b1e2697073d4c172d5a362a"),
    "trackingId" : "0050568a00bc",
    "environment" : "QA",
    "events" : [ 
        {
            "type" : "Status",
            "event" : "Not Sent",
            "eventDateTime" : ISODate("2018-06-19T08:04:22.603Z")
        }, 
        {
            "type" : "Status",
            "event" : "Ok",
            "eventDateTime" : ISODate("2018-06-11T08:04:19.606Z")
        }, 
        {
            "type" : "Status",
            "event" : "Initial",
            "eventDateTime" : ISODate("2018-06-11T07:36:55.632Z")
        }
    ]
}

我可以通过跟踪ID和环境db.getCollection('app.logging').find({"trackingId":"0050568a00bc", "environment":"QA"})

如何仅更新第一个eventDateTime的{​​{1}}？它必须与events，$push或$slice一起使用吗？
