Windows store lacking on unity

I have installed Unity 5.6.0f3 (after unistalling another unity that didn’t work at all) and I would like to use it for hololens development.

i have visual studio 2017 community installed previously (although I don’t understand what the Universal Windows Platform development workload(?) or the game development with unity workload means -as stated here Install the tools - Mixed Reality | Microsoft Learn )

However when going to Edit->Project Configuration-> Player I can not see the Windows store , and when I go to Edit->Project Configuration → Quality I don’t see the Windows Store mark either

What is the reason for this and how can I solve it? What is this windows store component I am missing?

When you installed Unity, did you install Windows Store module?
