[plugin development] create text object with attribut center

Hello everybody,
I am developing a custom plugin for adobe xd. It's a discovery for me. I'm creating a Text() object and would like to give it an "align = center" attribute. Is it possible ? I can't find it in the API.
my code:

    const txtPage = new Text();
    txtPage.text = "PAGE";
    txtPage.styleRanges = [{
        length: txtPage.text.length,
        fontFamily: "Montserrat",
        fontStyle: "Bold",
        fill: new Color("#2699FB"),
        fontSize: 24
    }];

Thanks in advance 🙂
