[Notifications] Display images attached in email

Problem statement:

From a user’s end, it won’t allow you to see any attached image unless log in if you’re replying on receiving notifications through emails, but that doesn’t seem like an issue for the App users.

Proposed solution:

Whether the picture can be displayed in the mailbox received by the user, so that the user can view the attachment in the email. Thank you!
