I have a requirement to implement the session timeout popup, if user is inactive for 5 mins and need to trigger the session popup with some message with 5 mins count down like 4:59, 4:58......00:00. and need two button one is "continue" and second one is "Logout".

when popup trigger first time on that time user can see only continue button and if user click on continue button, then counter should reset and popup will closed, and if user did not clicked on continue button, then within 5 mins popup will be closed automatically and user did not clicked anywhere in the application (Inactivity).then again after 5 mins we need to show the popup will trigger and this time user can see two button "continue" and "Logout" with 5 min counter and this time user will not take any action automatically application will logout.
we have Okta authentication which automatically logged out the application if user is inactive for 10 mins.

Our goal is by implementing this popup user have some time if user is inactive, they can increase the session time by clicking on continue button.
