Blank page after login and reboot of the page

I created an admin panel that requires login. After successfully logging in, the user is redirected to the appropriate page, but if the page was closed and then reopened in the browser, then a blank page appears and the only way to move forward is to directly specify the desired page in the URL.

What is “the appropriate page”? Is it different from “index” page?
Maybe you should configure On Application Start trigger and add “Navigate to”
