Question about the Zoho Assist program

Question about the Zoho Assist program

When a remote computer installs the small file to make the connection, does it automatically remove the program when the session is closed?  Is this a program install or a temporary process that is running?  I am trying to understand what takes place.  I want to be sure that the program does not leave files on the remote computer if it is only for a one time support session.
 
Thank you.
