Why is the SSH2 extension not displayed in the extension list of phpstudy?

Question

After the installation is completed, I have restarted apache many times but still can’t see it taking effect. How can I make it take effect?

I installed php_ssh2.dll but I can’t see it. Can you tell me how to make it effective?
