Using 3DPlay with Hololens 2

Hey there,
I'd like to use 3DPlay to stream my 3D models to my Hololens 2. Is it correct that I need to buy the 3DPlay app from the microsoft store and install it on my Hololens 2 and the workstation which I am using to stream?

I've already tried the other two 3DPlay apps within the 3DExperience respectively the browser but I didn't see any option for streaming.

Thanks in advance!

Best regards
