Can someone help me with Add-PnPPageWebPart with a custom web part?

[metkhoo]

I am trying to add my own SpfX web part to a page usng Add-PnPPageWebPart

I already have a current connection set up then I use;

Add-PnPPageWebPart -Page "MyPage" -Component ??? -Order 1

What goes in the ???
I have deployed my web part to the SharePoint AppCatalog and then Added it as an App in my site collection.

I have tried the following as ???

The name of the App as shown in Site Contents of the site
The ID as shown in the AppCatalog
The "name" parameter of the Web Part from the AppCatalog
The ID as shown from "Get-PnPApp"

None work for me
The error I get is:

Add-PnPPageWebPart : Value cannot be null.
Parameter name: component

I'm sure I am missing something really basic

Thanks in advance

OK if anyone else struggles with this the answer is that you need the TEXT of the Custom Web Part that is in the list of web parts as displayed when you add the web part to the page.
