Place Entity in the Middle of a Table in VisionOS

Hello Guys, I am currently stuck on understanding how I can place a 3D Entity from a USDZ file or a Reality Composer Pro project in the middle of a table in a mixed ImmersiveSpace. When I use the AnchorEntity(.plane(.horizontal, classification: .table, minimumBounds: SIMD2<Float>(0.2, 0.2))) it just places it somewhere on the table and not in the middle and not in the orientation of the table so the edges are not aligned. Has anybody got a clue on how to to this? I would be very thankful for a response, Thanks
