use with dynamic size, triggering with document scroll event

[GlauberF]

hello, I need to implement in a table where its size is dynamic, but it is inside a mat-tab, I would like to apply the virtual scroll to the table.
Remembering that I can capture the scroll event in the mat-tab and based on that do something.

See the GIF:

When loading the page, you can see that register up to item 3, that is, what is below item 3 I would like to apply virtual scroll.
And when you run the mat-tab scroll, load new items (4, 5, 6 ...) and apply the infinite scroll.
