Could also consider converting to a true/false value with:

const isLoggedIn = !!(user.auth?.isLoggedIn)

@joshua I was literally going to say the same thing.
I fail to see the point/usefulness of the '??' operator

There are always alternatives if you can also write

if(user.auth?.isLoggedIn === true){
    // user is logged in!
}

Nobody is forcing anybody to use the ?? operator but I think it just fits nicely together with the ?. and makes the intent clear if the developer knows how both of them work.
