I am considering starting with the free plan for my cloud kitchen business. Firstly, does the free plan include a fully customized WhatsApp chatbot? Also, do you know if I need to change the access token daily for chatting purposes in the free plan, or is this managed automatically? Also, do you know if the integration supports payment options directly within WhatsApp? Lastly, as I plan to take orders via WhatsApp, can I create a dish carousel to display my menu items effectively?
