@Himanshu Singhas many others said, it all depends on what you want to accomplish. If you want to run a full service desk like you have in big corporates, with, say, tens or hundreds of service desk agents, and thousands or tens of thousands of end users, then that organization probably already has an ITSM ticketing solution in place (such as ServiceNow, BMC Remedy, Jira, etc) and would be looking for an integration between Teams and that existing platform. In such case, a "single point of contact" could be made available via Teams to all the employees of such big corporate, under the form of a Teams App. When starting a chat session through that App, a chatbot could be triggered, ideally supporting multiple languages and automatic translation, and capable of Natural Language Processing. That chatbot could help users - based on how it was configured- and create or update tickets in the company's ITSM platform automatically, or, if needed, it could transfer the chat to a "human" service desk agent (depending on agent's skills and availability). On the selected agent's side, the chat would popup with an embedded support ticket from the ITSM ticketing tool and would provide several automations between the chat session and the ticket (such as pre-filling the employee's info or attaching transferred files automatically). Of course, this is a huge thing to build, but such solutions already exist: express-desk (www.express-desk.com) does all this and even more.
