Please consider this as a feature request to hide the Presence notification for users who do not require an Omnichannel security role to be assigned.

Currently, the system only allows to clear the notification error if an Omnichannel agent or supervisor role is assigned.

The notification error we would like to hide is "There was an issue delivering notifications. Refreshing the browser might help resolve the issue. If this continues to exist, please have your admin contact Microsoft Support..."
