How can I extract the code(content) of a <script>-Tag

Question

So I want to get the content of a script-Tag. I tried getAttribute, getText and other functions and variables, but it didn't work. I might have used them the wrong way.

This is my code:

const { Builder, By, Key, until } = require('selenium-webdriver');
const firefox = require('selenium-webdriver/firefox');

    (async function example() {
    
        const screen = {
            width: 1080,
            height: 720
        };
    
        let driver = await new Builder().forBrowser('firefox').setFirefoxOptions(new firefox.Options().windowSize(screen)).build();
    
        await driver.get('https://steamcommunity.com/market/listings/730/AK-47%20%7C%20Redline%20%28Field-Tested%29');
    
        let script = driver.findElements(By.xpath('/html/body/div[1]/div[7]/div[2]/script[3]'));
        
    
        script.then(() => {
            console.log(script);
        });
        
    })();

And instead of getting the script-Tag Content, I only get undefined.

This should be the result or atleast the most imporant part of it:

I hope that you can help me with this problem. Thanks in advance!
