If my keystone token expires after login from Horizon, will I be logged out during the operation?

Question

while analyzing Keystone Token in OpenStack Horizon, I have a question.

After login at Horizon, I confirmed that Horizon will logout after the Token expiration time even if session time is remaining. But all I checked is when I didn't do anything until the Token expiration time after login.

Even if I continue to work until the token expiration time after login, I wonder if Horizon will logout if the first token created expires. Or if I continue to work after login, I wonder if the token expiration time will increase or if a new token will be issued.

Or tell me about the source code location of Horizons so I can analyze more about the above questions.

Thank you.
