how to change SAML login user id

I am connecting to SSLVPN using forticlient 

I have setup SAML Login 

I can successfully connect , However I cannot change the user on my PC . I am doing some testing and would like to connecting using a few different accounts just to verify they are working as expected. 

How can i clear the credentials ? It appears like my Forticlient is remembering the SAML login with no way to change or clear it out .
