How to batch delete folder using PowerShell

Question

I'm trying to delete my OneDrive folder that is really large and has many nested folder with many items. I have this script but it's not able to handle a very large folder so just wondering how can I modify it so that It'll delete it by batch

I'm looking for an example elsewhere but couldn't find it yet so I would be really appreciated if anybody can help me modify or give me suggestion.

#Variables
$SiteURL = "OneDrive URL"
$ServerRelativeUrl= "/Zipped_Documents"


 
Try {
    #Get Credentials to connect
    $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Global:adminUPN, $Global:adminPwd)
    $ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $ctx.Credentials = $Credentials
   
    #Get the web from URL
    $Web = $Ctx.web
    $Ctx.Load($Web)
    $Ctx.executeQuery()
 
    #Get the Folder object by Server Relative URL
    $Folder = $Web.GetFolderByServerRelativeUrl($ServerRelativeUrl)
    $Ctx.Load($Folder)
    $Ctx.ExecuteQuery()
 
    #Call the function to empty Folder
    Empty-SPOFolder $Folder
 
    #Delete the given Folder itself
    Write-host  -f Green "Deleting Folder:"$Folder.ServerRelativeUrl
    $Folder.Recycle() | Out-Null
    $Ctx.ExecuteQuery()
}
Catch {
    write-host -f Red "Error:" $_.Exception.Message
}
