I believe this is something some of our clients have asked about previously, and one of my clients recently shared an article from Omnichat highlight WhatsApp Groups API offering, seem to be a new feature on their end: https://blog.omnichat.ai/whatsapp-groups-api/

from sales perspective, i think this could be a valuable feature for us to explore and offer to our clients as part of their communication workflows in some industries such as Interior Design/Events or internal team coordination/Prof Service.
