SharePoint Online: Loop Through All Subsites in a Site Collection using PowerShell

Requirement: Often while working with SharePoint Online using Client Side object model, we need to loop through each site site under a site collection and here is the PowerShell script to iterate through each subsite and get its title.

PowerShell CSOM Script to Iterate Through All Subsites in a Site Collection in SharePoint Online:
This script iterates through each subsite and list all subsite URLs.
#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"

#Variables for Processing
$SiteCollUrl = ""
#Get Credentials to connect
$Cred= Get-Credential
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
#Custom function to get all subsites in a given site collection
Function Get-SPOWebs($Url, $Credentials)
    #Set up the context
    $Context = New-Object Microsoft.SharePoint.Client.ClientContext($Url) 
    $Context.Credentials = $credentials

    $web = $Context.Web

    #Do Something Here
    Write-host $Web.URL

    #Process Each subsite in current site
    ForEach($web in $web.Webs)
        #call the function recursively
        Get-SPOWebs $web.Url $Credentials

#call the function                   
Get-SPOWebs $SiteCollUrl $Credentials
