Chatbot limitations

hi everyone, i just built a chatbot that can also send images or videos trough whatsapp business cloud send node. the only problem i have is that the limit is 1mb. I saw you can increase it to 16 mb by using the whatsapp media upload not the message send node. The workflow was completed without errors but i didn’t receive the video on whatsapp. Does anyone know how can i make this work? will i be able to extend the limit to 16 mb using a http request?
