Is it allowed? – Website/QR code on packaging

Thanks in advance for the help!

How serious is Amazon about NOT including links to your website on the product/packaging/inserts when you’re selling on their platform? Here’s why I ask:

• I’m selling a children’s product (I make it, so not a reseller). It is common, if not almost a requirement, that contact information be listed due to government regulations.
• It seems that other items in my category list their websites on packaging, even in their product photos used on Amazon.
• It doesn’t seem like other sellers are too concerned about this. Even outside of my product category, I see (as a customer) product inserts advertising discounts for purchasing direct, website addresses on packaging, etc.
• I will be selling on my own website as well.

It isn’t my aim to divert sales from Amazon to my own website. I just don’t want to have to create a separate SKU (different packaging, no inserts, no website etc.) just for Amazon. Thanks!
