How to make user access their 'user_session' table?

My application requires the user access 'user_session' table? How to make that table visible?

what you mean with 'user_session' table?

If you log into your database, you can do 'desc user_tables', user_session is also that kind of table belongs to sys. But I don't know how to make it usable

i never heared about user_session table ...
(however you can try with "select any table" grant)

What database version are you using ?
There is no user_session Table in Oracle 8 or 8i

you may want to look in v$session view
