Are there persistent AR anchors in HTC to anchor a virtual space in the physical space?

How do i anchor a virtual space in the physical space?

We are just starting out with Unity and probably have a simple question. We've created a room and we want the open end of the room to always point in a certain direction in the physical environment. The idea is that you sit in a virtual room and see the musicians in the physical room. At the moment, the room is always in a random position, aacording to the position of the headset. Any ideas?
We're using the HTC Vive XR Elite.

Thanks
