Populate language values for custom fields

[noodles]

Hey there,

I need to populate and save the custom fields (e.g. "title") via API, which works perfectly fine for the default language.
However, I can't manage to populate other languages.

So far I tried:

$img->title427468 = 'Hello Wereld';
$img->save();

Nothing is saved. Other notations

Another approach:

$languages->setLanguage('dutch');
$img->title = 'Hello Wereld';
$img->save();

This indeed saves "Hello Wereld" to the dutch custom title field, BUT however DELETES the content in the default title field.

The "setLanguageValue"-function is non-existent for the images/files, so it doesn't help.

 Can anyone help? ?
Thank you very much. ❤️

Anyone any clue? I still have no idea how to achieve this. ?

This should be quite straightforward: https://processwire.com/docs/multi-language-support/multi-language-fields/#getting-and-setting
