What is a proper way to call UI control method from ViewModel

[Aleksey1555]

Hello.
I want to create Visual Studio Extension for Debugger Visualizer, and i want to use WebView2 control for render HTML page.And i need to render HTML page from string.There is method NavigateToString which can do this, but the because of in VS Extension VSSDK is using MVVM pattern - i have no access by name to WebView2 control. So, how i can call this method?

My configuration:
Window 10 x64
Visual Studio 2022 Community
Type of project - VisualStudio.Extensibility Extension with VSSDK Compatilibity
.Net Framework 4.8
Microsoft.VisualStudio.Extensibility.Build - version 17.12.40390
Microsoft.VisualStudio.Extensibility.SDK - version 17.12.40390
Microsoft.VisualStudio.SDK - version 17.12.40392
Microsoft.Xml.Behaviors.Wpf - version 1.1.135

Also: i am try to create modern type of Visualizers by using class DebuggerVisualizerProvider.
Please help!
