What's the general rule for Amazon Text Links?

Hi guys, just a quick question. I know that for pictures/CTA buttons. We need to specify that the link will be going to Amazon or else the account can get banned.

What about for articles that are not "Best Product Guides" but more of an informational article and you just want to place an affiliate link through the text. What's the general rule for a text link? Should I also specify that they are going to Amazon?

Like should the link be something like "buy Vitamin D brand name in Amazon"

Should all text links have to specify that they are actually going to Amazon?
