Solution

okay so all of these people saying you cannot access app specific folders, are absolutely wrong, heres how u do it:

Step 1: get the permission of the folder you want,

public void openDirectory() {

String path = Environment.getExternalStorageDirectory() + "/Android/data/com.pubg.krmobile/whatever folder you want to access";
File file = new File(path);
String startDir, secondDir, finalDirPath;

if (file.exists()) {
    startDir = "Android%2Fdata%2Fcom.pubg.krmobile%2Fthefilder%2Fsubfolder%2Fdeepersubfolder";
} 

StorageManager sm = (StorageManager) getSystemService(Context.STORAGE_SERVICE);

Intent intent = sm.getPrimaryStorageVolume().createOpenDocumentTreeIntent();


Uri uri = intent.getParcelableExtra("android.provider.extra.INITIAL_URI");

String scheme = uri.toString();

Log.d("TAG", "INITIAL_URI scheme: " + scheme);

scheme = scheme.replace("/root/", "/document/");

finalDirPath = scheme + "%3A" + startDir;

uri = Uri.parse(finalDirPath);

intent.putExtra("android.provider.extra.INITIAL_URI", uri);

Log.d("TAG", "uri: " + uri.toString());

try {
    startActivityForResult(intent, 6);
} catch (ActivityNotFoundException ignored) {

}}

step 2: write an onactivityresult to get the path

public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    
    if (resultCode == RESULT_OK) {
        if (data != null) {
            uri = data.getData();
            if (uri.getPath().endsWith(".Statuses")) {
                Log.d("TAG", "onActivityResult: " + uri.getPath());
                final int takeFlags = data.getFlags()
                                              & (Intent.FLAG_GRANT_READ_URI_PERMISSION);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    getContentResolver().takePersistableUriPermission(uri, takeFlags);
                }
                
                // these are my SharedPerfernce values for remembering the path
                prefHelper.setIsScopePermissionGranted(true);
                prefHelper.setSavedRoute(uri.toString());
                
                // save any boolean in pref if user given the right path so we can use the path 
                // in future and avoid to ask permission more than one time
                
                startActivity(new Intent(this, MainDashboardActivity.class));
                finish();
                
            } else {
                // dialog when user gave wrong path
                showWrongPathDialog();
            }
            
        }
    }}

step 3: Get the files one by one from here

 if (Build.VERSION.SDK_INT >= 29) {
            // uri is the path which we've saved in our shared pref
            DocumentFile fromTreeUri = DocumentFile.fromTreeUri(context, uri);
            DocumentFile[] documentFiles = fromTreeUri.listFiles();
            
            
            for (int i = 0; i < documentFiles.length; i++) {
                documentFiles[i].getUri().toString() //uri of the document
                }
            }
        }

and voila, you now have access to that folder using the path saved in shared prefrences
