Create flow using Flow but run flow in Excel Flow Add-in

Is it possible to create a flow using Flow and run it inside Excel's Flow Add-in?

I am following https://flow.microsoft.com/en-us/blog/introducing-microsoft-flow-integration-in-excel/

But rather than create my flow using the Add-in as described in the URL above, I'd like to create my flow using Flow.

I then want to run that Flow from My flows in the Excel Flow Add-in (see right panel of the image below).

Is this possible?

If I create the Flow using the Add-in, it does show up in the right panel. 

But I want to start my flow using a template which I can only find when using Flow.  I am thinking perhaps the reason I cannot find that template is because the Add-in is not capable of using it.

Thank you for reading.
