It is not a bug but I really want to have an answer

[JafferArshad]

can we just read a file from ios files application without opening it into the unity application

I'm a bit confused; can you elaborate? Is your Unity app automatically opened when you click on a specific file in Files app? Do you want to just pass a "string filename" to an API and want it to fetch the file with that filename automatically, without opening the native dialog? Or something else entirely?

This isn't possible with this plugin. On latest Android versions, I'd say that it's impossible without the MANAGE_EXTERNAL_STORAGE permission which is "very restricted" if you're planning to publish on Google Play. I have no clue about iOS.
