[Resolved] I need multilanguage email. Tutor lms and wpml

Background of the issue:
I need multilanguage email support for my site hidden link using Tutor LMS and WPML plugins. Tutor LMS doesn't support sending messages in the user's language. I tried to make changes myself using the documentation provided by WPML. The code I used is as follows: public function course_enroll_email_to_student( $course_id, $student_id, $enrol_id, $status_to = 'completed' ) { $enroll_notification = tutor_utils()->get_option( 'email_to_students.course_enrolled' ); if ( ! $enroll_notification || 'completed' !== $status_to ) { return; } $student = get_userdata( $student_id ); if ( false === $student ) { return; } $user_language = get_user_meta( $student->ID, 'icl_admin_language', true ); if ( ! $user_language ) { $user_language = 'en'; } do_action('wpml_switch_language_for_email', $user_language); $course = tutor_utils()->get_course_by_enrol_id( $enrol_id ); $enroll_time = tutor_time(); $enroll_time_format = date_i18n( get_option( 'date_format' ), $enroll_time ) . ' ' . date_i18n( get_option( 'time_format' ), $enroll_time ); $course_start_url = tutor_utils()->get_course_first_lesson( $course_id ); $site_url = get_bloginfo( 'url' ); $site_name = get_bloginfo( 'name' ); $option_data = $this->get_option_data( self::TO_STUDENTS, 'course_enrolled' ); $header = 'Content-Type: ' . $this->get_content_type() . "rn"; $header = apply_filters( 'student_course_enrolled_email_header', $header, $enrol_id ); $replacable['{testing_email_notice}'] = ''; $replacable['{user_name}'] = tutor_utils()->get_user_name( $student ); $replacable['{course_name}'] = $course->post_title; $replacable['{enroll_time}'] = $enroll_time_format; $replacable['{course_url}'] = get_the_permalink( $course->ID ); $replacable['{course_start_url}'] = $course_start_url; $replacable['{site_url}'] = $site_url; $replacable['{site_name}'] = $site_name; $replacable['{logo}'] = isset( $option_data['logo'] ) ? $option_data['logo'] : ''; $replacable['{email_heading}'] = $this->get_replaced_text( $option_data['heading'], array_keys( $replacable ), array_values( $replacable ) ); $replacable['{email_message}'] = $this->get_replaced_text( $this->prepare_message( $option_data['message'] ), array_keys( $replacable ), array_values( $replacable ) ); $subject = $this->get_replaced_text( $option_data['subject'], array_keys( $replacable ), array_values( $replacable ) ); ob_start(); $this->tutor_load_email_template( 'to_student_course_enrolled' ); $email_tpl = apply_filters( 'tutor_email_tpl/student_course_enrolled', ob_get_clean() ); $message = html_entity_decode( $this->get_message( $email_tpl, array_keys( $replacable ), array_values( $replacable ) ) ); $this->send( $student->user_email, $subject, $message, $header ); do_action('wpml_restore_language_from_email'); }

Symptoms:
Tutor LMS doesn't support sending messages in the user's language, and the changes I made using WPML documentation didn't help.

Questions:
How can I make Tutor LMS send emails in the user's language using WPML?
What additional steps can I take if the provided WPML documentation doesn't resolve the issue?
