Trouble using wipe everything command

[ramyrover]

Maybe i have misinterpreted the meaning of the command, but i am looking to clear messages from both parties of a private message session. So far i have only been able to clear my own messages with no luck deleting the other entities sent messages. Please do inform if this is possible to clear the other entity messages.

Used command : tgeraser session "xxx" -w --entity-type "user" && tgeraser session "xxx" --wipe-everything --entity-type "user"
