How to use the @theia/filesystem/lib/browser/filesystem-watcher.FileChangeType.DELETED function in @theia/filesystem

switch (change.type) {
                case FileChangeType.UPDATED:
                    for (const [id, subscriber] of this.subscribers) {
                        if (!subscriber.ignoreChangeEvents && this.uriMatches(subscriber, change)) {
                            subscriber.proxy.$fileChanged({ subscriberId: id, uri: theiaUritoUriComponents(change.uri), type: 'updated' });
                        }
                    }
                    break;
                case FileChangeType.ADDED:
                    for (const [id, subscriber] of this.subscribers) {
                        if (!subscriber.ignoreCreateEvents && this.uriMatches(subscriber, change)) {
                            subscriber.proxy.$fileChanged({ subscriberId: id, uri: theiaUritoUriComponents(change.uri), type: 'created' });
                        }
                    }
                    break;

                        this.go(location, false, false);
