trying to get Text2d to work in a 3d scene under Bevy 0.15

[smurfer]

I want to use Text2d to draw labels next to certain entities in 3d space. As a test, I combined the Text2d example https://github.com/bevyengine/bevy/blob/latest/examples/2d/text2d.rs with the simple 3d Scene example https://bevyengine.org/examples/3d-rendering/3d-scene/, replacing " commands.spawn(Camera2d);" with spawning a 3d camera.
The 3d scene shows, but the Text2d entities do not. I then re-added the camera2d with a render order of 1, which results in drawing the Text2d example on top of the 3d scene. But of course, the 2d Text cannot be translated in the z direction.
Can someone enlighten a Bevy and Rust beginner on how to draw Text in 3d space?
