Google Workspace
Calendar, Drive, Gmail.
Google Calendar
Sidebar then Integrations group then Google Calendar (or `/google-calendar`). Follow OAuth. External events appear read only in `/calendrier`. You can enable propagation so events created in Nexte also land in Google.
Google Drive
Sidebar then Integrations then Drive (or `/drive`). Connect your account. You can then attach Drive files to projects, proposals and clients without uploading.
Gmail
Sidebar then Integrations then Gmail (or `/gmail`). Follow OAuth. Emails linked to your contacts are synced and appear in `/messagerie` and the client page. Atlas can then suggest replies.
