Listing was approved for children’s category but can you update images and detail page?

This is our first time selling on Amazon and we are just getting started with FBA. Are selles allowed to add additional images and one more bullet point to the product detail page after kids toy product after it was approved?

I am asking this question because Amazon wrote in the email response after it was approved the following statement….

Please note that all images and mandatory attributes (e.g., age recommendations, cautionary warnings) must remain accurate and consistent with the approved details. If you update your detail page with unapproved information, we may deactivate your account/ remove your product listing(s) and/or take any additional action(s) we find necessary at our sole discretion.

That is the part that I am lost with. Well what if you want to add a couple more images or extra notes. Just want to check before we do any further steps.
