Can we send all the information regarding user profile from Frontend to LivePerson using JWT?

Options

Problem I am facing here is when User A chats and logs out, then User B starts a chat in the same browser, some of User A's information may persist in cache — leading to: Incorrect personal info being shown for Users. What I am thinking here is If I can send the users information through JWT as JWT will be generated unique for each login, so the problem I am facing might be resolved.

I am open for suggestions for better solution for this problem or what can be done in this scenario. Any leads will be appreciated.
