How to delete a document that has a subdocument in firestore database?

Here is the collection structure

enter image description here enter image description here I would like to delete the document doc("3F0SezA3")

I tried these below but none had work, i am getting console.log('deleted') but in the database the document is still showing

firebase.firestore()
    .collection("users")
    .doc("3F0SezA3").delete()
    .then(function () {
                console.log('deleted');
              }, function (error) {
                console.error('Delete Error', error);
              });

 firebase.firestore()
.collection("users").doc("3F0SezA3")
.collection("movives").doc("asdrftgyqweAsdghj120a").delete()
.then(function () {
                console.log('deleted');
              }, function (error) {
                console.error('Delete Error', error);
              });

If you want to delete the two documents at the same time, the best is to use a batched write, as follows:

var batch = firebase.firestore().batch();

var parentRef = firebase.firestore()
    .collection("users")
    .doc("3F0SezA3");
batch.delete(parentRef);

var childRef = parentRef
    .collection("movives")
    .doc("asdrftgyqweAsdghj120a");
batch.delete(childRef);

batch.commit()
.then(function () {
    console.log("Docs deleted")
})
.catch(function (error) {
    console.log(error)
});
