How to get all Nintex workflows which contain Call Web Service actions using Powershell (SP 2016)

Hi,

I would need to get all Nintex worklows (name, location) of any kind (list, site, reusable, ect) deployed on my SharePoint 2016 Server which contain Call Web Service actions using Powershell.

Is it something possible to achieve ?

Thanks,
