WO document upload

Hello,

I am new to this and I got some code from support to upload documents to Work Orders.

My question is what do I use to upload a document when the PDF file is accessible by UNC path.

<int:StorageTypeId>URL</int:StorageTypeId>
<int:DocUrl>https://www.jllt.com/wp-content/uploads/2021/12/ms-badge_v3-01-1024x871.png</int:DocUrl>
<int:MimeType>Sample.png</int:MimeType>
<int:WonId>0</int:WonId>

I was told that I can change the StorageTypeId to 'Local' but the only documentation I can find for Local is using Blob data.

Any help would be greatly appreciated.

Thank you
