Until recently, Siri could only process dictated messages in chats with individual people. With yesterday's update, version 2.18.80, she can now also participate in groups.
And this is how it works:
- Activate Siri and tell her that you want to send a WhatsApp message
- When Siri asks you for the contact, tell her the group name
- You can then dictate the message and approve it again before sending
- After approval, the message will be sent
