Get count of all the subsites (all levels) in all site collections in SharePoint Online using PowerShell

问题

I'm trying to get all site collections and respective subsites at all levels within the site collection using PowerShell. There are so many posts and references which outline the way but I could not find a post which can provide the count of subsites (all levels again) in a site collection. My environment is SharePoint Online. I need two things:

Get the count of all subsites in all site collections in SharePoint Online and export to CSV.
Export the list of site collections and subsites in the format Site Collection URL | Subsite URL.

Please note that irrespective of the level, the first column in the CSV should have Site Collection URL.

I've tried the following code but not able to get it to work. Please help me out.

#Add the PowerShell module
Import-Module Microsoft.Online.SharePoint.PowerShell

#Load SharePoint CSOM Assemblies

Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"

Try {
    Function Get-SPOWebs($SiteURL)
    {

        $SiteCollURL = $SiteURL

    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Credentials

    #Get the web
    $Web = $Ctx.Web
    $Ctx.Load($Web)
    $Ctx.Load($Web.Webs)

Change your code to this, check if it works:

    Function Get-SPOWebs($SiteURL)
    {

     $SiteCollURL = $SiteURL

    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Credentials

    #Get the web
    $Web = $Ctx.Web
    $Ctx.Load($Web)
    $Ctx.Load($Web.Webs)
    $Ctx.ExecuteQuery()

    #Do something
    Write-host $Web.Title "-" $Web.Url  
    $SubsiteResult = new-object PSObject
    $SubsiteResult | add-member -membertype NoteProperty -name "SiteCollURL" -Value $SiteCollURL
    $SubsiteResult | add-member -membertype NoteProperty -name "SubSiteURL" -Value $Web.Url
    $SubsitesResultSet += $SubsiteResult

    $WebsCount++

    #Loop through each each subsite in site
    Foreach($Web in $web.Webs)
    {
        #Call the function again to get all sub-sites in the site (web)
        $WebsCount=Get-SPOWebs($Web.Url)+1
