Question on indentation in JS files Follow

I want WebStorm to refactor JS file like this:

const a = [
    {name: 'BackgroundContainer', scaleStrategy: ['cover-screen', 1920, 1920], children: [
        {name: 'background', type: 'sprite', image: 'background.jpg', scale: 1.01}
    ]}
]

But it keeps doing that:

const a = [
    {
        name: 'BackgroundContainer', scaleStrategy: ['cover-screen', 1920, 1920], children: [
            {name: 'background', type: 'sprite', image: 'background.jpg', scale: 1.01}
        ]
    }
]

I have not found any setting to tune this behavior after many hours of search.
