Impulse theme - adding a wave svg to a section

[greentigershop]

Hi all,

I'd like to add a wavy line like this for my site. 

After researching, I found that I could create a svg file and add to my site's code.  The code is pasted below. 

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1440 320">
  <path fill="#c9d9af" fill-opacity="1" d="M0,288L80,250.7C160,213,320,139,480,133.3C640,128,800,192,960,224C1120,256,1280,256,1360,256L1440,256L1440,0L1360,0C1280,0,1120,0,960,0C800,0,640,0,480,0C320,0,160,0,80,0L0,0Z"></path>
</svg>

I'd like to modify the section below. How do I go about doing this? I'm not a designer/coder.

My site: https://greentiger.co/

Add Custom Liquid and then paste your svg code

@wo I do not have that option. Is it something I have to add in the codes first?
