The Cross-Sell App can be translated but requires some customizations.

Integrations will have to be requested through a 3rd party like StoreTasker by parsing the metafield data from the Cross-Sell App through custom liquid code like the one attached.
Please get in touch with Storetasker to help you with the required change.

If you have any further questions regarding the Cross Sell App, don't hesitate to contact their Support Team at support@csell.co.
