forticlient ems connection

Dear team, could you help me with the following scenario.

We have a PC that is used by two users (each has their own VPN account). However, when user X wants to log in to the VPN with his account, he cannot because the other user's account is saved.

In this case, the first time they logged in, the access to the person who logged in to the VPN was saved.

The problem is that now that another user wants to use the same computer with his account, he automatically logs in with the other account that he logged in the first time at the Forticlient level and the login interface does not appear.

Could you tell me where I can configure Forticlient EMS so that it can request credentials from the user who is going to connect each time he logs in?
