Problem mentioning a user in Zoho Desk API

Problem mentioning a user in Zoho Desk API

Hello !
I would like to ask for help.
I'm trying to make a request to the Zoho Desk API, URL: https://desk.zoho.com/DeskAPIDocument#TicketsComments
To create comments and would like to mention a user, according to the documentation you need to send zsu[@user:{zuid}zsu . Could someone tell me what an example would be so I can do it here.
Thanks !
