How to add custom Grass to the Scene in HDRP?

[BYFo_Max]

I'm using 2020.3.23f1 HDRP and Gaia 2021 Pro.

When I add to the Grass Details directly under the terrain a new Detail, then it's shown as white planes like the others.
But when I switch to Playmode they are invisible.

When I add the Grass as new TerrainDetail in the Alpine Meadow-Grass Script, then it's shown as white planes like the others.
But when I switch to Playmode they are invisible.

What is the correct workflow? By the way here the *.png I'm using as well.

Thanks in advance 🙂

You could try and make a custom flora for it. 
Unity doesnt handle grass in HDRP thats why we created Flora.

That did solve it somehow. It kept disappearing sometimes, but I got it to work eventually after some tweaking.
