Logout user after a set period of inactivity for angular embedded in asp.net mvc application

Question

I have asp.net MVC 4.8 enterprise application which having 60% angular component code and 40% C#, cshtml page.

Application having owin cookies based authentication, let say it has managed to log out in 2 min.
IAppBuilder.CookieAuthenticationOptions.ExpireTimeSpan =2 minutes

Scenario:

1. If a user has opened angular page and idle for more than 2 min, login page not been re-directed automatically.
2. If a user has opened asp.net mvc page and idle for more than 2 min, login page get redirected automatically.
3. If a user has opened angular page and page having background api call for every 5 seconds , login page not been re-directed at all.
4. If a user has opened asp.net mvc page and page having background api call for every 5 second, login page not been re-directed at all.

As solution : I have implemented below code in common javascript file

var USER_INACTIVE_SINCE = 0;//IN MINUTE
var IDLE_TIME_ALLOWDED = 10;//IN MINUTES

function checkUsersActivity() {

setInterval(function () {
    USER_INACTIVE_SINCE += 1;
}, (1000 * 60));//1 MINUTE INTERVAL
$(window).focus(function () {
    USER_INACTIVE_SINCE = 0;
});
$(window).blur(function () {
    USER_INACTIVE_SINCE = 0;
});
$(document).click(function () {
    USER_INACTIVE_SINCE = 0;
});
$(document).keypress(function () {
    USER_INACTIVE_SINCE = 0;
});

}

function IsUserActive() {
    return IDLE_TIME_ALLOWDED > USER_INACTIVE_SINCE;
}

to stop background call let say in 1 min in case of user inactive below code has been implemented in each and every file.

this.intervalTime = setInterval(() => {
            if (IsUserActive()) {
                this.CheckUserOnline(); //api call
            }
        }, 5000); //every 5 seconds

Problem : Using above implementation I have managed all scenario except user experience. until and unless user doesn't click on page (which have background api call) after idle time (let say 2 min) login page doesn't get redirected automatically.
