missing i18n translation

[nelero]

Preconditions

1. Magento 2.4.3
2. mc-magento2 103.4.62

Steps to reproduce

Put the shop in french (or any other non english language)
run composer update mailchimp/mc-magento2
There is no i18n folder in the vendor folder dedicated to mailchimp module.

Actual and Expected result

So some messages are still in english.
Why there is no translation in most used languages ?
