Send LemWatch alerts to a Google Chat space via incoming webhook.
https://chat.googleapis.com/v1/spaces/AAAA/messages?key=...&token=...
Your Google Workspace admin must allow incoming webhooks for the space. If the Webhooks menu is missing, ask your admin to enable it under Admin Console → Apps → Google Workspace → Chat → Chat apps and integrations.
Alerts render as Google Chat cards with the site name, severity-coloured header, current metric values, and a button that opens the LemWatch dashboard.
