launch new InPrivate mode instance of edge and with InPrivate tab open

[myusrn]

We currently have start shell:AppsFolder\Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge that will start a new instance of edge and use an start shell:AppsFolder\Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge <some url> that will use existing instance of edge if present to open url.

We also have start microsoft-edge: and `start microsoft-edge:<some url>" that always takes one to existing instance of edge if present either and existing instance with new tab pointing at specified url.

With either of the above we can set %lt;some url%gt; = about:InPrivate to get an InPrivate tab but not the <existing edge instance> | ctrl+shift+p experience of a new InPrivate instance of edge with InPrivate tab open. There are hits suggesting the first of the above options can be fed a -private switch to accomplish this but all it does on my current win10 setup is take me to a search page with -private search results.

Any thoughts on whether or not your work here could be updated to focus on providing a command line version for reproducing the <existing edge instance> | ctrl+shift+p experience ?
