First ask write permission
And no need read permission

To request permissions they must be declared in the Manifest.
To ensure this (in your case), add the File component and enable WritePermission in the properties of the Designer.

WRITE permission is no longer available on Android 11+. However, storage permissions for the shared folders (such as /Download, /Documents) are no longer required on Android 11+.

Note:
WRITE_EXTERNAL_STORAGE is sufficient as it implicitly grants READ permission.
