🐛 Bug Report: Notification messages are getting missed during Concurrent Notifications Request

[Dushyant-YM]

📜 Description

When we trigger multiple notifications at the same time or within few seconds, we do not get all the notification messages in events provided by novu hooks. When we reload the page or next event comes then some or all missed messages comes in that particular event.

👟 Reproduction steps

1. Trigger Novu API (https://api.novu.co/v1/events/trigger) for concurrent requests from JMeter tool.
2. See messages/ data provided by Novu hooks(useNotifications, useFetchNotifications or useSocket notification_received event) on client side.
3. sometimes we miss messages or sometimes we get all messages then again repeat from step 1.

👍 Expected behavior

1. We should get all messages in events , no messages should get dropped.

👎 Actual Behavior with Screenshots

1. Messages should not be missed in events even though there are concurrent notifications.

Novu version

v0.19.0

npm version

9.5.0

node version

v18.15.0
