Adding HTML with clickable links to my store?

I am working with an affiliate partner, (first time). They emailed me the links to use in my listings, and after much reading and videos, I’m feeling like I might be overthinking this. I cannot figure out how to add this correctly.

In my Shopify theme-Edit Code for HTML; for my products inside my store, I don’t have any of the suggested file types for product.liquid. I have product.grid-item.liquid, product.rv.liquid, product.quick-view.liquid, and product.json, these are all under the templates list. Under the sections list I have; product-template.liquid

Three of my HTML’s have a clickable image and the text description. I added these to the Assets folder along with my Banner images. I don’t know if they belong there.

Thanks for any help you can offer.

Do these: Add HTML links in Shopify Admin (no coding needed):

Go to your product in Shopify admin

In the description box, click “Insert link” or paste the HTML code they provided

Save

And If you must edit liquid files:
Use product-template.liquid (in Sections)

Look for the product description section

Add the HTML links there

For clickable images:

Upload to Assets folder

Everything loaded smoothly. I found 2 places that could be the product description/product info section, in the tab for >product-information.liquid. 1)

For possible hint on which to use?

Kindly state what you need and i will try as much as possible to answer

Thanks for your help.

I found 2 places that could be used for

product-information.liquid.

“product-information__section” and

“product-information__content”

Which one do you think should I try?
