You can integrate Garoon with Cybozu Office (custom app).
For details on custom apps, see Custom app feature on the product site.

Cybozu Office is available only in Japanese.
For this reason, custom app screens are displayed in Japanese regardless of the user's display language settings.
The time zone settings in Garoon do not apply to custom apps.
For details on setting up Garoon integration with custom apps, see Custom App Connector Guide.
