Fires during Drupal's language negotiation process when the ECA language negotiation method is active.

Set the langcode to override the negotiated language. If left unset, this negotiation method is skipped and the next method in the chain is consulted.

Must be enabled in language settings

The ECA language negotiation method must be enabled at Administration > Configuration > Regional and language > Languages > Detection and selection.
