Curved Planar Reformat module is not exist

Operating system: Windows 10
Slicer version: 29738, 4.11
Hello everyone,
I’ve recently started to use 3D Slicer and was looking for a curved planar reformat to straighten the aorta in a planar, but I could not install it as it is not found in my extensions manager and sandbox as well. my slicer version is 29738
May I get some guidance, please?

Thank you so much
