Seeking Advice: Book category = No Advertising, how to rank organically

I learned today that my children’s books are ineligible for advertising. Supposedly this is for the entire ‘book’ category. Feeling very stupid for not having checked this before, but it did not even cross my mind this would be the case.

What are my options? I could change the category since these are interactive books that toe the line between game and book, but I think I could be really competitive in the current category since these are such unique products.

Is there anything I am missing as potential levers I can pull? How can book products grow organically and index if you cannot pay for the attention that is so hard to get as a new product. Is it all really just about funneling marketing from off-Amazon to your listings?

Appreciate any help – this is all quite overwhelming.

And if anyone wants to assess/critique my listings, Id appreciate any insights: https://www.amazon.com/s?i=stripbooks&rh=p_27%3AFable+Fox+Press&s=relevancerank&text=Fable+Fox+Press&ref=dp_byline_sr_book_1
