Receive Google Chat app event
Receives classic Google Chat interaction events and Google Workspace add-on events, then verifies a Google-signed OIDC ID token. Add-ons require the callback URL audience and the exact per-project add-on service account; classic apps trust Google’s Chat service account and can use a legacy project-number audience. It auto-links unambiguous verified-email memberships, returns REQUEST_CONFIG to classic apps or basic_authorization_prompt to add-ons when user confirmation is needed, treats a plain connect message as an explicit reconnect/add-workspace request, consumes manual fallback setup messages, and revokes links when the app is removed from a DM. Google supplies configCompleteRedirectUrl for classic events or configCompleteRedirectUri for add-on events. This endpoint does not accept Atoll API keys.
