Small adjustments to woocommerce webshop through oxygen builder

Hi! I'm looking for some help making small adjustments to my Woocommerce webshop through oxygen builder. Specifically, I need help with the functionality of the webshop, but no existing content or media needs to be updated. I'm also not sure if a third party plugin needs to be integrated or not. If you have the experience and know-how to help with this project, I'd love to hear from you. Thanks!
