How do delete conversations by sender_id?

Hi, i send a rest request to my rasa api by accident, so the wrong conversations with a sender_id " [object Object]" is saved like the screenshot, so how can i delete it? i have explored all the rasa api and rasax api, but no one looks like can do it.

EDIT: I have achieved this by deleting some data from the tables “message_log” and “conversation” in the database file rasa.db.
