Do you have a photo of your bike's drivetrain?

It appears as if the chainring is bolted on with 4 bolt spider. That should mean that the chainrings are replaceable, and you should be able to source larger rings if you have the actual specs (or can measure it).

Does your bike use a cable guide? Is there any adjustment?

If you can return your bike, perhaps take a day or two to look at alternatives, and it may be the best option.
