Help with an old .kext

Hello! Can someone do me a favor and upload this file for me. I'm making a mod of a 2006 imac and I want to get the camera to work. I have searched the Internet for several days but I can only find another file with the same name but it is not the .kext. It would be someone who will use an inferior version of Big Sur. There's a kext located at IOUSBFamily.kext/Contents/PlugIns by the name of AppleUSBVideoSupport.kext that will load the required firmware to make the camera work. Thanks
