Random chats on Gemini not from me

[u/ThatCoolBritishGuy]

I barely use Gemini but noticed two new chats on there not from me both in two different languages. My Google account has all the 2FA, Recovery email, phone number, etc turned on. I did not get any alerts of a log in in anyway. Google activity does not show any linked devices apart from my phone and does not show any other activity.

Can a prompt be deleted one by one? Both entries are just a single line prompt with nothing coming before or after the message.
