Dual access to accounts, how to sign out

my friend gave me access to her Zoom page so I can start a meeting if she is going to be late. I also have a Zoom page. However, when I sign in to Zoom using her meeting ID, I always come up as her instead of signing in as me.

Other members of our group use her private meeting ID but sign in as themselves. I need to sign in as me  as a participant and not the host. Can you help Please!
