How can I make a button trigger a Javascript popup (Divi + ActiveCampaign)

I just got off support with ActiveCampaign and they said they couldn't provide me with code examples on how to add their modal pop-up forms to be triggered by wordpress buttons.

I found a few resources online but they are all slightly different than the functionality I'm looking for.

I already added the ActiveCampaign plugin to my wordpress site and there are two options of embedding the form within the site.

1. shortcode "[activeCampaign formId=1]" or

2. <script src="https://exampledomain.com/f/embed.php?id=1" type="text/javascript" charset="utf-8"></script>

I'm currently using the divi theme, and the buttons have sections for CSS ID's and CSS Classes.

so to summarize, I would like to be able to click a button and have the activecampaign modal form popup.

If you could show me how I can add code to the button and my site to trigger the modal popup that'd be amazing.

Let me know if you have any other information.

Thanks!
