How do I apply environment variable to turn on HTML report on analyze?

[JinsPeter]

Experimental Features shows that we can turn on experimental features using environment variables. But I don't understand how to apply this env variable.
Should I do it globally on my computer or is there an option to apply it to the dotnet tool itself - like the way a new .NET Core solution like uses launch setting to add env variables?

Should it be done during installation? Should it be done on running analyze?

Can we have a example command?

It should be added before an invocation of the tool. You may add them globally or per console window.

For example in PowerShell:

$env:UA_FEATURES="SOLUTION_WIDE_SDK_CONVERSION"
upgrade-assistant features --list

Outputs:

[11:18:11 INF] 'ANALYZE_OUTPUT_FORMAT': False
[11:18:11 INF] 'ENABLE_CROSS_PLATFORM': False
[11:18:11 INF] 'SOLUTION_WIDE_SDK_CONVERSION': True
