.net core 2.2 session timeout

I have .net core app deployed azure app service Linux container. The problem is session timeout. One of the user group want no session timeout. The application is shared among different user groups so I don't want to extend the session timeout to hours. Even though I extend, it depends on server pool recycle time. So I add some java script to keep the browser alive. But it doesn't help too. Kindly give any suggestion whether it is possible or not.
