How to close Modal after action run

I have this ‘Glance’ Action on the appointment table which show a modal with the infolist. At the footer of the modal I have added two action buttons ‘Approve’ and ‘Reject’. I want to close the modal which was opened by glance action when user either click on approve or reject action button. Which is not happening now. After click action is running but not closing Modal. How can I manage that? P.S Dont know how to paste my code here.
