Document reload when open modal on the same page

Hey i am using cyntler / react-doc-viewer, the issue i am facing that in my react mui app i have place document in a page and also a delete button when clicking on delete or edit button it opens the modal for confirm deletion, but at the same time it reloads the document and when modal is closed it agains reload the document. but if i use iframe for pdf rendering or video tag for video rendering it does not rerender or reload when modal is open or close on same page. how to avoid rerendering please.
