Trying to access csv file in iOS device

Hello.
I have made an application in unity in which data is stored in .csv file format and saved in a location using the path as Application.persistentDataPath(). I have created many .csv files with this method.

Now, I want to access those .csv files but I am not able to access those using the same Application.persistentDataPath() method.

Is there a way to access those files or do I have to try some other way to save and retrieve the files?
