Hello @thepiyush-303,

Has the behavior changed for all messages, or only for messages with attachments like audio, video, files, and images?

For normal text messages, the current delete modal works well by displaying the message content in the modal. However, for messages with attachments, it simply displays the attachment. We can improve this by showing the filename and file description along with the attachment.

This would give the user a clear understanding of which message they are deleting.

Currently, the following texts are displayed:

1. Are you sure?
2. You will not be able to recover this message!
   While both are based on RC terminology, they do not provide the user with a clear idea of which message they are actually deleting.

The approach mentioned above would certainly enhance the UI and improve the user experience.

I think we should follow Rocket's behaviour in EC also, rest will be decided by @Spiral-Memory
