Delete contact and chat messages

[mrjackson6969]

I run app on Ubuntu 22.04.3
On right click on person i have:
-Delete Messages
-Delete Conversation
-Delete Contact
Which one of those suppose to delete messages on both sides? All on my side and those I sent on the other side? From my experience none work. I don't know, I tried to used them all, and all it does it to delete messages in my app but other people can still see the old chat. And when i recover account on new device I have access to old, deleted messages.

Right now the only way to delete messages for yourself and your chat partner/s is to right click on a message and select "Delete for everyone" or select messages and "Delete for everyone". There is no option to right click on a conversation and delete all messages for everyone

What is the difference between "Delete contact" and "Delete conversation"? It both look like it deletes messages from the device but not from servers.
