Concrete Under Patch Question

[Rusty Wrench]

I poured a small stair landing pad oversized by mistake. Pavers will abut to the edge and the look is to have no concrete visible.
I made a cut with 4 in angle grinder and diamond blade. The cut looks ok but hammering fractured it off 1.5 to 2 inches inside and under. A bit further in than I'd like. The face of the first riser will be flush with the cut.

I think I need to patch fill it in and wondering whether to use the vinyl patch stuff or the Quickcrete ready-to-use mix that I poured.
Or something else?
Thanks

I don't think you need to do anything. that void won't cause an issue

If you’re installing pavers, fill in and compact the area with sand, same as pavers.

Thanks Fellas.
Looking at it again; I agree.
