can't get Grant-PnPAzureADAppSitePermission to work

[JeWi78]

Hi,

I'm attempting to grant write permissions to an Azure Ad registered application using Grant-PNPAzureADAppSitePermission. When I call the cmdlet

`Connect-PnPOnline -url $URL -interactive

Grant-PnPAzureADAppSitePermission -AppId $appid -DisplayName $Displayname -Permissions write -Site $URL

Get-PnPAzureADAppSitePermission -Site $URL
`

The output I get is :

Id : aTowaS50fG1zLnNwLmV4dHw3YjU1YWMxOS05NzUwLTQ0MjQtYTAwYi1jZGEwZTA0YjVjYTVAMWJjYWExYjYtMTBhMy00ZmMyLWEwODYtOTJlNjc2MGEzMDIw
Roles : {write}
Apps : xyz

Roles :
Apps : xyz

It looks like the Grant is working, but when I check the roles with get-pnpazure.. the roles are empty.

Hopefully someone here can help me out!
