ReactJs for only specific pages in Laravel

I want to use react for specific pages in my laravel application. Im using Laravel as fullstack stack. So im using standard html-css-pure js flow.

But in my specific pages (i have some calculator etc.) i want to use react, to manage state easily. Is there any way to do it without creating bearer token flow.

When I connect react, i want to get all my session data. is that possible?
