  description: 'The Google Chat REST API lets developers build Chat apps that send messages,

    manage spaces and members, post cards, handle slash commands, react to

    events, and integrate external services into Workspace conversations.

    Authentication uses OAuth 2.0 user credentials or service-account credentials

    for app-bot calls.
