Fixed package visibility for Android 11 devices
Android 11 introduced new package filtering so when v1.18 was released which bumped target sdk to 30 many apps were not visible in Notification plugin setting. I added QUERY_ALL_PACKAGES to fix this issue.
Here is Android Documentation regarding the same. As mentioned in the documentation a form needs to be filled out if you use this permission.
There are other types filter too but I don't think they will fulfill the needs of the app as it needs to query all the packages to get notifications from apps.
