JotForm Lightbox - I have a form on my companies website but I am unable to change the position attribute

Is there a way to inject custom CSS in an embed code for a form? Below is our current form and it works great, but we want it to stay in the center of the screen until the user clicks off of it:

add_action('wp_footer', 'loadJotFormQH');

function loadJotFormQH(){ ?>

<div class="test2020">

    <script src ="https://form.jotform.com/static/feedback.js" type="text/javascript">

        var JFL_201906943035049 = new JotformFeedback({

          formId: '201906943035049',

          base: 'https://form.jotform.com/',

          windowTitle: 'Form',

          background: '#FFA500',

          fontColor: '#FFFFFF',   

          type: '2',

          height: 650,

          width: 800,   

          openOnLoad: false

        });</script></div>

<?php }

I see font color, background, height, etc. Is there a way to put "position: fixed;" Or is that not possible? 

Steps to recreate:

-Go to the stage site https://stage.quakerhoughton.com/

-Click 'x' on the popup

-Click the Contact Us button

-Scroll down and see that it is not fixed position, but absolute

Have you tried using our updated lightbox code? In the updated version, the lightbox has a fixed position by default. To try the updated version you can get the fresh form lightbox code, or add 2 to the feedback script.

I have tried that, it results in a jquery clash and breaks my sticky menu. Is there another way? 

Greetings.

I have tried to access your site, and I get a 403 forbidden error. 

However, I have copied the code you have provided, and I was able to replicate the problem. I tried to fix the element, but since the JavaScript generates new div at the end of the page, without any classes or IDs, I was not able to fix it. 

As an alternative, we can suggest you a pop-up form.

Thank you for your understanding.
