You can receive important ticket updates and instant notifications when a ticket is escalated, happiness rating is received, ticket is closed etc. by customizing the channel notifications in the bot.
You will get notified in the Teams whenever an action is performed in the associated Desk portal and department. For instance, if the same ticket is handled by multiple agents and an agent replies to the ticket in the Zoho Desk portal then you will get a notification card in Teams along with the ticket details.
Within the card, users (admins or agents) can perform the following five operations:
Send Reply - Reply to the ticket from within Teams.

Add Comment - Add a new comment to the existing comment thread in the ticket.

Assign Owner - Change or assign another agent as the ticket owner. Also, you can assign the ticket to another team for the customer ticket.

Update Status - Update the ticket status to completed, re-opened, and in-progress for the desired customer ticket.

View Ticket - Agents or admins can view the respective ticket to which they have access in detail.

Note:
By default, the administrator has the privilege to perform all of the above five operations.
Agents can access only those functions that are assigned to their profile in Zoho Desk.
The update status command can't be performed in MS Teams if a Blueprint is mapped with the tickets module in Zoho Desk.
