PnP cmdlet doesn´t send edgeaccesscookie to ADFS Proxy

[mobidarabbit]

Reporting an Issue or Missing Feature

If we connect-pnponline to our On-Prem SharePoint 2019 (behind ADFS and WAP) via -UseWebLogin (works) and than call e.g. Get-PnPSite, the Request of the Cmdlet gets redirected (seen in fiddler) to Authenticate again by Web Application Proxy. Because of that, the Cmdlet fails.

Expected behavior

The cmdlet should use all cookies (fedauth & edgeaccess) from the connection, to be able to pass the ADFS Proxy.

Actual behavior

Cmdlet doing requests just with the fedauth cookie, not how expected with fedauth and edgeaccesscookie.

Steps to reproduce behavior

The Issue reproduces if the cmdlet has to pass Web Application Proxy, which is publishing SharePoint, configured with Preauthentication on ADFS.
