Switch user account

Hello!
So I have used an old account and want to switch to my new one. I am starting CATIA 3DExperience through the 3D Experience Online Platform / Dashboard (with my new account), however it always starts my CATIA with the old account. 
Can I somewhere sign out? Or delete the local cache, so that it does not automatically connect with my old account?
Best regards
