Trying to return a user dependent language

I have created an email function which sends custom emails to users.
This function retrieves some acf fields from the current language, but I tried to do it in a batch instead of getting the email templates just once instead of again for each user.

I wanted to do this by language code. The steps are

1. query all active languages
2. foreach through these languages
3. get all users which are about to expire and have set language (in loop item) as preferred
4. change current language to language (in loop item)
5. get email template for this language (in loop item)
6. loop through users and send email
7. change back to original language after (languages) loop

$eot_benchmark = date( 'U', strtotime( '+8 days', current_time( 'timestamp' ) ) );
$users         = [];

// get active countries
$all_languages    = apply_filters( 'wpml_active_languages', null, [] );
$hidden_languages = apply_filters( 'wpml_setting', [], 'hidden_languages' );
foreach ( $all_languages as $key => $values ) {
    if ( ! array_key_exists( $key, $hidden_languages ) ) {

        // get all users which have set $key as preferred language
        $user_args = array(
            'role__in'     => array( 'independent', 'company' ),
            'role__not_in' => array(),
            'meta_query'   => array(
                array(
                    'key'     => 'sd8_vip_eot_date',
                    'value'   => $eot_benchmark,
                    'compare' => '<',
                ),
                array(
                    'key'     => 'sd8_vip_eot_date',
                    'value'   => date( 'U', current_time( 'timestamp' ) ),
                    'compare' => '>',
                ),
                array(
                    'key'     => 'sd8_preferred_language',
                    'value'   => $key,
                    'compare' => '=',
                ),
            ),
            'number'       => -1,
        );
        $users     = get_users( $user_args );

        
        if ( class_exists( 'SitePress' ) ) {
            // if this language has any users who set $key as preferred language
            if ( count( $users ) > 0 ) {
                add_filter( 'acf/settings/current_language', function() {
                    return $key;
                } );
            }
        }
        
        // do email stuff

        if ( class_exists( 'SitePress' ) ) {
            add_filter( 'acf/settings/current_language', function () {
                return ICL_LANGUAGE_CODE;
            } );
        }
    }       
}

4 is the one I am struggling with. I can’t get $key to return the correct language (code). I know this isn’t the proper way to do it, but it illustrates what I’d like to achieve.

I have a way to do it, but it isn’t the most ideal one, because it’s not DRY.

if ( 'nl' == $key ) {
    add_filter( 'acf/settings/current_language', function() {
        return 'nl';
    } );
} elseif ( 'en' == $key ) {
    add_filter( 'acf/settings/current_language', function() {
        return 'en';
    } );
} else {
    add_filter( 'acf/settings/current_language', function () {
        global $sitepress;
        return $sitepress->get_default_language();
    } );
}
