"WinSCP" WinSCP 5.x using a key to connect to the server

In WinSCP 4.x, the main page has an option to add an encryption key file, as shown in

But the main interface has changed a lot in the WinSCP 5.x.

There is no option to load the key file on the home page, so how do we use key verification?

WinSCP 5.x integrates pageant for key verification, we click Tools, run Pageant (P), and then in the notification area in the lower right corner of the desktop we will see the pageant icon

We right click on the pageant icon and find the Add key option to load our key file.
