I need to execute a powershell script onChange or onSubmit of catalog client script

[SUHASM]

Dear developers, 

I have a powershell script which works fine in flow action. However, I need to execute that snippet in catalog client script as onChange or onSubmit script. By doing that, based on the response of that script, form will be allowed or denied submission. 

I am okay to execute that PS script as a flow action or Script Include or Business rule. 

Could someone please help me here?

Thanks,

you can trigger that flow action via script using GlideAjax

syntax here

You can also open that flow action, click 3 dots and click Create code snippet and use that script
