What do you mean by sideloading? If you're sideloading an OTA then TWRP isn't necessary. You can simply sideload by following instructions on the Google OTA page. The critical unlock is used to root your phone. This allows you to install TWRP, and flash a factory image, or other boot image to your device. Technically, this is rooting, not sideloading.
