Microsoft Edge WebView2: Private Mode / Incognito mode

Hi! Since it's now possible to make use of Microsoft Edge WebView2, we wanted to switch several Google Chrome sessions to the new feature.

We use that especially with all of the new Microsoft 365 Admin portals, for example: https://admin.microsoft.com/ & https://security.microsoft.com/ & https://endpoint.microsoft.com
The problem is, as an MSP, we have to login to plenty of different tennants. With the embedded Chrome incognito mode, this is possible. Each tab makes use of it's own credentials.
With Edge you stick to the session/credentials you launched the firs session with. If I now launch the 365 admin portal of a different tennant, i'm still logged on to the first tenant.

With embedded Google Chrome it's possible to set the switch "Private mode (Incognito)". I would like to see that with Edge WebView2 as well.
Thank you!
