Grant Access to 1 machine for 2 users

Grant Access to 1 machine for 2 users

We have an issue where 2 ZoHo Assist users need access to the same PC for a duration of time. (One user is training the other and both will need access to the one PC)

In installing the free version, it wouldn't allow 2 users to have access to the same PC. Is there a way around that?
I had to say it was OK for the installer to replace to prior person's email/account for the new person.

Thank you
