In order to test the distributed file service functions of application A and application B, the developer installs application A and application B on both device 1 and device 2. During the test, application A on device 1 creates a distributed file X, and application B on device 2 creates a distributed file Y. Which of the following descriptions of this scenario is wrong?

With distributed file services, application A on device 1 is able to read and write file Y on device 2

If Device 1 and Device 2 are logged in to different HarmonyoS accounts, distributed file sharing cannot be implemented

For the non-sensitive permissions declared by the application in the config.json file, the application will be dynamically applied for during use

Non-sensitive permissions declared by the app in the config.json file are automatically granted when the user installs the app

For the non-sensitive permissions declared by the app in the config.json file, the authorization method is user authorization (user_grant).
