Allow control allow origin add-on for chrome install offline

My work place does not have internet connection and I want a Chrome add-on named “Allow control allow origin”. I read there is a CRX file which can be used to install add-on offline. So what I planned is I will download the CRX file at home and mail it at my work email ID and install it from there. But I am not able to find the CRX file download link. Can anyone help me with a proper download link for CRX file? OR is there any other way I can use this add-on offline?
