Adding new property bag item in SharePoint Online

In SharePoint online when you try to add a property bag via pnp powershell, you will notice that you get the following error

Set-PnPPropertyBagValue : Site has NoScript enabled, and setting property bag values is not supported
At line:1 char:1
+ Set-PnPPropertyBagValue -Key "KEY_XYZ" -V ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (SharePointPnP.P...ropertyBagValue:SetPropertyBagValue) [Set-PnPPropertyBagValue], Exception
    + FullyQualifiedErrorId : NoScriptEnabled,SharePointPnP.PowerShell.Commands.SetPropertyBagValue

As the error says, we need to disable NoScript property by running the following command

Connect-PnPOnline Site Collection URL

Set-PnPTenantSite -Url Site Collection URL -NoScriptSite:$false     

After running the above command you should be able to add your new property bag item using the following command:
         Set-PnPPropertyBagValue -Key "" -Value "" 

PLEASE NOTE : Connect-PnPOnline command is very important, without this even you were already logged in the NoScript property cant be set to false. It sounds strange but that is what i experienced.
