async function fails to push to array

Question

I have used a for loop but all the functions get triggered at once, the array.push is not working obviously and I get empty as results

 const results = []
    for (let x in obj) {
        const url = 'https://api.test.com/v2/text?image_url=' + encodeURIComponent(obj[x]);
        (async () => {
            try {
                const response = await got(url, {
                    username: apiKey,
                    password: apiSecret,
                });
                results.push({ response: response.body, url: obj[x] })
            } catch (error) {
                console.log(error);
            }
        })();
    }
    console.log('results :', results);
