For interaction with the TDLib you need to create an instance of a class `TdClient`, providing a handler for incoming updates and other options if needed. For interaction with TDLib you need to create an instance of the class `TdClient`, providing a handler for incoming updates and other options if needed.
After that you can send queries to the TDLib instance using the method `TdClient.send` which returns a Promise object representing the result of the query. Once this is done, you can send queries to the TDLib instance using the method `TdClient.send` which returns a Promise object representing the result of the query.
