I'm having trouble setting up my WhatsApp channel in de config. I tried this setup but when I run "nullclaw channel start whatsapp" the following message is shown:

No messaging channel configured. Add to config.json:
Telegram: {"channels": {"telegram": {"accounts": {"main": {"bot_token": "..."}}}}
Signal: {"channels": {"signal": {"accounts": {"main": {"http_url": "http://127.0.0.1:8080", "account": "+1234567890"}}}}

This is my current channels config:

  "channels": {
    "cli": true,
    "whatsapp": {
      "accounts": {
        "main": {
          "dmPolicy": "pairing",
          "allowFrom": [
            "+31xxxxxx"
          ],
          "groups": [],
          "groupPolicy": "allowlist",
          "groupAllowFrom": [
            "+31xxxx",
            "+31xxxx"
          ]
        }
      }
    }
  },

It would be great if someone could point me in the right direction.
