Refactoring to convert && chain to optional chain expression

interface Foo {
    bar?: {
        baz?: string;
    }
}

declare let foo: Foo | undefined;

[|foo && foo.bar && foo.bar.baz|]

It should be possible to convert that chain into the following:

interface Foo {
    bar?: {
        baz?: string;
    }
}

declare let foo: Foo | undefined;

foo?.bar?.baz;
