How to make third-party plugins work in webbrowser?

Question

ActiveX

There is a program that opens a web page through a web browser. The site uses ActiveX. If you enter through IE, then there is a request to use a third-party imageviewer plugin that is installed on your computer. If you accept the request, then the site works correctly, if not, then it's crooked.
In webbrowser, this confirmation window does not appear. I allowed everything in the browser properties, so everything works immediately in ie, but it didn’t work in webbrowser. How can I programmatically make the webbrowser accept a plugin activation request?
