Hi,
please add support for the Ecovacs Deebot X8 in the official ecovacs: integration.
• Model code: 4bx3w9
• The robot is not currently recognized by the integration.

I’ve captured the communication between the Ecovacs app and the cloud using mitmproxy, including:
• GET/POST requests
• Model ID and device ID

I’m happy to share this data or help test if needed.

Thanks in advance!
Jakob
