Acceptance criteria

• New users: If the plugin was enabled on the workspace, new users get a bot message from the Google Calendar bot prompting to connect their google account the first time they log in.
• Existing users: When the Google calendar plugin is enabled, DM existing users prompting them to connect their google account. Ensure that the DMs are not sent all at the same time to avoid any performance issues, sparse messages or run a job in batches.
