They are not the same. The event published by things service is a notification that a thing has been connected or disconnected from a channel. The event published by connectThingEvent and disconnectThingEvent in bootstrap are an acknowledgement that a thing has been connected or disconnected from a channel

While trying to assign parent group for channel , like below request

curl --location 'http://localhost/channels/795b0be8-f8d9-4101-a40f-859ed573c71c/groups/assign' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer <Token>' \
--data '{
    "group_ids" : [ "5c6de392-6dc4-46fc-8e2c-e6f4ce4fffab" ]
}'

In events received below logs, which use group.assign operation , the same operation is used for thing connect, so could not different between thing connection event and group assign channel events

[#8] Received on "events.magistrala.things" with reply "_INBOX.7g7jymtBXH0wOSok79kUGo.0LlN1Z1P"
*�{"group_id":"795b0be8-f8d9-4101-a40f-859ed573c71c","member_ids":["5c6de392-6dc4-46fc-8e2c-e6f4ce4fffab"],"occurred_at":1714131210669902557,"operation":"group.assign"}

Additionally,

In the event message group_id filed contains channel id
actually here we should have group id

In member_ids field , it contains
group_id , actually here we should have channel id
