How to fix "Invalid Add-on" error when installing unpublished Gmail addon?

I developed a Gmail addon on my personal Google scripts workspace. I didn't have any trouble installing it on my personal Gmail. I haven't published it to the app marketplace yet and I wanted to install (using this method) it on my company's Google Suite email account (I am the administrator of that Google Suite account). However, when I copy the deployment ID and press install I get an error saying "invalid addon".

I have made sure that:

  1. My work email account has read access to the google scripts folder with the code
  2. Security preferences allow third party marketplace apps on the

Any guess on how I can solve this?
