🧪 Testing

Using both XML and Compose demo apps:

• Open a channel.
• Long-press any current user message.
• Click on the "Delete Message for Me" option.
• It should show "Message deleted" and show the "Deleted only for me" label.
• It should not delete the message for the other chat members.

For different visibilities when a message is deleted, you can change deletedMessageVisibility:

DeletedMessageVisibility.ALWAYS_VISIBLE:

• It should show the "Message deleted" for all the members when a message is deleted.
• It should show the "Message deleted" + "Deleted only for me" label for the current user only.

DeletedMessageVisibility.ALWAYS_HIDDEN:

• It should not show the "Message deleted" nor "Deleted only for me" when a message is either deleted or deleted for the current user only.

DeletedMessageVisibility.VISIBLE_FOR_CURRENT_USER:

• It should not show the "Message deleted" for all the members when a message is deleted.
• It should show the "Message deleted" + "Deleted only for me" label for the current user only.

Changing deletedMessageVisibility:

Compose

Update MessagesActivity.factory to change the deletedMessageVisibility

XML

Update ChatFragment.initMessageListViewModel to setDeletedMessageVisibility
