Course Enrollment Filter or Hook in Tutor LMS

I have Tutor LMS free version. I have developed membership functionality on my website. When a member is logged in and a new paid course is published, it should show free to member. I have made the course free through the below filter.

add_filter(‘get_tutor_course_price’, function($price, $course_id) {
if (is_user_logged_in()) {
$user_id = get_current_user_id();
if (user_has_membership($user_id)) { // The function to check membership
return 0; // Make the course free
}
}
return $price;
}, 10, 2);

But when member clicks on “Enroll Now” button, he doesn’t get enrolled.

Is there any filter or hook I can use for this?

Thanks & Regards.
