Camera lens calibration failed in Virtual production

Hi, I am working on virtual production, first of all I want to do the camera lens calibration, just follow the website: Camera Lens Calibration Quick Start Guide | Unreal Engine 4.27 Documentation

However, in step 1, I can’t find the “camera calibration” plugin

if I skip that, I can’t find the checkerboard in step 2:(

My question is… is there any official camera lens calibration plugin can be downloaded? Or should I switch to other version? (Now I have 4.27)

Any advice is appreciated!
