Gmail Add-on

The Workestra Gmail Add-on adds a sidebar panel to Gmail compose windows. Users pick a booking link, offered slots, or a team page, and the add-on inserts a Workestra snippet into the message body.

Copy the source from apps/gmail-addon/.
Configure the script properties required by your Workestra environment.
Deploy a test deployment for validation or an internal Workspace deployment for assigned users.
Install the add-on for the pilot or organization from the Apps Script or Google Admin deployment flow.

The package source lives in apps/gmail-addon/ of the Workestra monorepo. The package README documents the clasp-based deployment workflow.
