What can I make with cassava flour

Maybe you can make queijo de pao which is Brazilian cheese puffs, https://www.thekitchn.com/how-to-make-po-de-queijo-brazilian-cheese-bread-cooking-lessons-from-the-kitchn-176118

Otto's may have recipes on their websites. Cassava flour makes nice tortillas.

I realize this is a rather conservative approach but I would see if the product manufacturer has some suggestions on usage.

For example, Bob's Red Mill has a recipe database here:

https://www.bobsredmill.com/recipes

where one can search for "cassava". One would hope that these recipes have been well tested by the mill.

Best of luck.
