New discoverable space setting in Google Chat

Previously, spaces were either private (invite-only) or open (anyone in the organization can find and join). Discoverable spaces provide a new option between the two: they appear when users browse for spaces within their organization, but the conversation history and messages remain private until an owner or manager approves a user's request to join.

This update helps organization leaders and community managers build groups that are easy to find without sacrificing data privacy. For instance, this setup is ideal for employee resource groups, specialized internal committees, or project teams that want to maintain an organization-facing presence but require membership vetting before sharing ongoing discussions.
