Add or Update SharePoint solution to site

[lipalath-ms]

I'm working on creating a PowerShell script to deploy SharePoint package to app catalog and install solution to site:

I have the following script:

        Connect-PnPOnline -Url "https://<tenant>.sharepoint.com" -Credentials $credential -TenantAdminUrl "https://<tenant>-admin.sharepoint.com"
	Add-PnPApp -Path $Path -Scope Tenant -Overwrite -Publish	   
   	$packageInSite = Add-PnPApp -Path $Path -Scope Site -Overwrite -Publish
	Publish-PnPApp -Identity $packageInSite.Id -Scope Site      

After running the above script I can see the package getting deployed to app catalog:

What script updates are required to ADD/UPDATE solution to site (ADD IT/GET IT automatically)?
