The telnet invoke command lacks detailed guidelines

When the telnet invoke method contains a custom object, you need to specify the class as the key. The key contains the object's completion object name, such as org.apache.dubbo.Persion.

Start by locating the telnet invoke documentation in the Hugo site and read the surrounding guidance for custom objects. Update the documentation to explain that the key must use the object's completion object class name, such as org.apache.dubbo.Persion; done means the custom-object invocation guidance is explicit.
