Share Request API

Share Request API

Hello, I'm trying to write a script to share / un-share request on ServiceDesk Plus using API and PowerShell.
I can't find informations about share request API into the documentation, but following this old thread (https://pitstop.manageengine.com/portal/en/community/topic/share-request-using-api) I'm trying to use JSON structure suggested without success.

Can anyone help me suggesting an official KB or script example?
Thanks in advance.
