Here is an example for people who want to understand:

add_filter('acf/validate_value/key=field_65067bde5086e', 'checkEmails', 10, 4);
add_filter('acf/validate_value/key=field_65067e4f26db1', 'checkEmails', 10, 4);

function checkEmails($valid, $value, $field, $input_name){

    if(!isset($_POST['acf']['field_65067bd15086d'])) return $valid;

    $email = $_POST['acf']['field_65067bd15086d']['field_65067bde5086e'];
    $confirmEmail = $_POST['acf']['field_65067bd15086d']['field_65067e4f26db1'];

    if(
        !filter_var($email, FILTER_VALIDATE_EMAIL)

        ||

        $email !== $confirmEmail
    ){

        return 'test';
    }

    return $valid;
}
