Writing file in USB Drive in android

Question

I am trying to copy a file from my app to USB Drive(Pen drive) in Android but I am getting the Permission denied.

I have already given runtime storage permission.

Process: com.testapplication, PID: 19261 java.io.FileNotFoundException: /mnt/runtime/write/02EE-0EE1/Tele-calling list.xlsx (Permission denied) at java.io.FileOutputStream.open0(Native Method)

Manifest

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_MEDIA_STORAGE" />

Code

val cacheFile = File(cachepath, it.name)
val pendriveFile = File(pendrivepath, it.name)
Log.d(TAG, "********: " + cacheFile.path)
Log.d(TAG, "&&&&&&& " + pendriveFile.path)
cacheFile.copyTo(pendriveFile)
Toast.makeText(context, it.name + " copying..", Toast.LENGTH_SHORT).show()

I am facing issue in cacheFile.copyTo(pendriveFile) line. Pendrive path is "/storage/02EE-0EE1" that I have calculated in runtime.
