It is always a good idea to contact OSS to get as much information as possible about your rejection.
In this case, the most recent rejection was because of invalid metadata. Specifically, icon.png that is listed in the `icons` section of your manifest.json was not able to be loaded. I don't have access to the package that was uploaded, so I can't confirm the problem.
Additionally, based on the notes from the earlier rejection it looks like the extension is using Firebase auth. I assume they already have, but it would be worth making sure your developer followed the steps discussed in the
github issue to address all of the problems with that as of today.
