Can't Alter Widget Images

I believe I got the plugin from this thread:

https://colorlibsupport.com/t/cusomizing-parallax-widget/

However, I do not see the plugin there.

I would like to be able to add html code to the parallax sections to embed items or customize the font, colors, sizes etc of each section.

One example is the instagram feed:

On this site www.cypressstakeyouth.com/test has the non-updated shapely with that plugin and you can see how I am able to embed the feed there to look how I would like.

On the site I am trying to set it up on cypressstakeyouth.com I have it using a different widget because I could not embed the feed. I would really like to be able to have the same functionality as before if possible.
