Hello, I'm trying to develop an outlook add-in for my company that detects if there are external recipients in the to, cc, or bcc columns. I have developed all of the necessary files (HTML and JS) but I have not been able to figure out how to organize my manifest. I have a Dev tenant to which I would like to push this app in my Microsoft Admin center but every time I attempt to upload my manifest it does not work. If there is anyone knowledgeable on manifests, please let me know if you can take a look and assist. Thanks! :)
