I want to write a custom component for community with separeting notifications by day.

Hi everyone! I completed the trailhead module "Build an Instant Notification App". My code was successfully verified, bur after getting one notification message I get an error from cometd.js library (3.1.1 version):
 08:29:24.933 Exception during handling of messages Unrecognized advice action handshake     cometd:1332
Any ideas how to fix it or did somebody have the same issue?

Hi,
I am trying to find the different events upon which we receive notifications under the Bell icon.

Some of them I have observed so far is
a. When there are Chatter mentions
b. Approval Request notifications
c. Transaction Security notifications

Q1. Are there any other events upon which we might be receiving the notifications? 

Q2. Can we configure custom notifications to be appearing under the bell? For example, change of status field on a cutom object.  We can configure email alerts using Workflows or Process Builder, but I am also looking if I can be notified in Salesforce, for different events.

Appreciate any pointers. Thanks in advance.
