Hello savinus,
All the front-end content and strings are full editable in the plugin page, including button, checkbox labels, etc.
In the .pot file you can translate the hardcoded strings and the default content if the plugin is installed without saving the options in the admin area.
This means, if you translate the “Strictly Necessary Cookies” in the .pot file, and you switch the language the translated version will be displayed in the admin area only.
This plugin has WPML support, so you can use the input fields in the admin area to translate your content and labels, but from .pot file you can translate the hardcoded admin strings (these are not editable but are not visible in the front-end)
