Auth0 is authenticated access token React SDK

I am a beginner in using this library for my react app. I am trying to simulated cookies expiry logout functionality with auth0 but every time I refresh the page the access token seems to refresh with a new one. The isAuthenticated from react auth0 sdk has an expiry time of 1day that I am unable to change.
The getAccesstokensilently generates new token every time. Confused with this now.
Anyone can assist me with this regard.
