Niagara in Hololens 2

I am having issues getting my Niagara systems to show up in Hololens 2 packaged projects. Remoting works puuurfectly but packaged projects just do nada nada limonada.

Question:
How does one permit Niagara systems to work with packaged projects for Hololens 2 for UE5?

P.S. I’m trying both CPU and GPU systems to no avail.

Update:
I verified that Niagara worked just fine in an old UE4.27 project I had lying around… So what’s the dealio with UE5?
