Zoho WorkDrive - Disable Button/Folder

I have been able to successfully make use of the Share Files/Folders to everyone on the Internet API request.

I took the link generated and placed it in an iframe.

It shows the relevant folder however that folder is within another folder or is nested.

So the folder that is loaded inside the iframe is for example labelled 'Customer Brand Perception' but that folder is within another folder/nested in another folder labelled 'NCB'.

I don't want the user to be able to click on the NCB folder and go upwards/see what's inside that folder.

I'd like for the user to not be able to click on it or be able to see the contents inside the NCB folder.

<?php

include("zoho-work-drive-refresh-token.php");

$department_brand_folders = [

'Customer Brand Perception' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'Lorem Ipsum' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

];

if (array_key_exists('Customer Brand Perception', $department_brand_folders)) {

$resource_id = $department_brand_folders['Customer Brand Perception'];

$token = $value["access_token"];

$postFields = array(
'data' => array(
'attributes' => array(
'resource_id' => $resource_id,
'shared_type' => "publish",
'role_id' => "6"
),
'type' => "permissions"
)
);

$curl_url = "https://workdrive.zoho.com/api/v1/permissions";
$data_to_post = json_encode($postFields);
$curl_variable = curl_init();
curl_setopt($curl_variable, CURLOPT_URL, $curl_url);
curl_setopt($curl_variable, CURLOPT_POST, 1);
curl_setopt($curl_variable, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_variable, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl_variable, CURLOPT_POSTFIELDS, $data_to_post);
curl_setopt($curl_variable, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $token, 'cache-control: no-cache'));

$response = curl_exec($curl_variable);

$err = curl_error($curl_variable);
if ($err) {
echo "cURL Error #:" . $err;
} else{
$data = json_decode($response,true);
$link = $data['data']['attributes']['permalink'];
}

} else{
echo '<br>';
echo '<pre>';
echo "ERROR";
}

?>
