How can I find all the workflows in my O365 SharePoint tenant using PowerShell

[Jeff-SP-Admin]

How can I find a list of Nintex workflows being used in all my site collections in SharePoint Online/O365 using PowerShell? I have seen a few solutions referenced back in 2015 for on-prem. Do you have an updated solution for O365/SharePoint online? 

Any help would be greatly appreciated.

There is a PowerShell script that has been tossed around in the community. I will try and find it.

If you have access to Nintex Hawkeye, I would also attempt that if you can.
