Using custom webpart as ListView's web part dynamic filtering source

Hi everybody,

I've developed a custom web part using SPFx. I want to show to my users the content of a specific folder defined in a document library.

Inspired by the article about dynamic data (https://docs.microsoft.com/en-us/sharepoint/dev/spfx/dynamic-data#consume-dynamic-data-in-web-parts), I'd like to take advantages offered by the dynamic filtering defined in the Document Library WebPart, that I thinks works as described in the linked document.

Unfortunately I can't find an article or a class in the API that helps me to define the correct interface.

Can anyone help me?

Thanks very much!!

Samuele
