Occasional Visitor

Hi. I have two organization accounts and I accidentally joined a meeting of one organization(A) using the account from the other organization(B), not sure if the administrator of the meeting did something to let me in. Now there are two chat members in that meeting and one of them is shown as external. They have my account information such as email, which is not I wish. How can I remove that external account?


I tried several solutions. First, there is no chat shown in the account for org. B. Even if I joined the meeting again, there is no button to leave (I can see the button to leave the chat in account A, ironically). Other than that, organization A doesn't appear on my settings of account for B, so there is no way to remove it.


If no easy solution is possible, would it work if organization B delete and re-create my account?
