How to add a particular script in the 'body' HTML on a specific page?

[shashaankaachaarya]

I am trying to add a particular script (Chargebee to be precise) in the body HTML of the pricing plans page.
I can successfully add another script in the Header through Page HTML Header of the page settings.
However, I cannot find any option to add another script in the body HTML of the page.

If I choose the SEO / metatags under Settings, the script will be added to all pages I guess, which I don’t want.

Any help? Any workaround to achieve this?

Add it to an HTML element.

It is not working.
However, when I copy paste both the scripts in Header (need to include two scripts - one in Header & one in Body), it does work!

I want to call the JavaScript function on a button click (like Subscribe Now).
