Could you please fix the Delphi Demos. They are not working for a long time over many versions.
The Parameters are incompatible.
Also is the concept of the demo with frames VERY difficult to understand.

Maybe also add a minimal demo that just has just that code required to connect via SSH, with lots of comments explaining what is happening when and what the various values represent. Don't use any clever events or lots of includes, just have one form with all the required components and a single button that sets all the links between components, hard codes property values and opens the connection. Then we can easily substitute our own values for the properties and learn how to set up a connection.
