Why a media library not shown in Wordpress and images are not uploaded into the media library?

Media library is not displayed neither I can upload nor I can see the uploaded media files. So kindly help me out to this situation.

If you already have files in the uploads folder and want to add them into the database, you can use this plugin to add files from server.

don't upload file directly to upload folder upload it by backend which will not added media information to database.

React Native - Upload Multiple Image Files in a Single Call

I am referring to this post on react native image upload to server: How to upload Image on server using ReactNative
Other than workaround of calling fetch multiple times for multiple image files upload (looping through the files), I was wondering how to upload multiple of image files by just calling fetch once? Could someone provide a simple example?
Thanks in advance!
