Display SharePoint Online URL, Site Owners (full control including any in Office 365 groups)

Hi All,

I'm using PNP modules to iterate through each subweb so I can extract into a file the following information for each site:

URL, Site Title, Owner/s

I need to script to go through each site and find the users that have full control permission and I also need to go into any office 365 groups that are attached to the site and display those names too.

I have attached what I have so far however the groups and names are currently just pulling all from the site collection - not what I need which is I need to pull the full control permission list of users who are attached to each site.

Sorry for the very basic script - I am just starting to delve into PowerShell!

Connect-PnPOnline -url "team site"

$Sites = get-pnpsubwebs -recurse
$Groups = Get-PnPGroup
$UserList = Get-PnPUser

$FileUrl = "c:\temp\SPOSiteList.csv"

#Write CSV- TAB Separated File) Header
"URL, Site Name, Groups, Users" | set-content $FileUrl 

foreach($web in $Sites){
"$($web.url), $($web.Title)" | out-file $FileUrl -Append

foreach($groupname in $groups){
", , $($groupname.title)" | out-file $FileUrl -Append
}
foreach($user in $UserList){", , , $($user.title)" | out-file $FileUrl -Append
}
$sites.dispose()
$groups.dispose()
$UserList.dispose()
}

Thanks in advance!
