How to add reactive data to scopes? (Vue)

How I should add reactive data to scopes? Is it possible?

When I attach “static” data to Scope it works fine, but when I attach the store, it keeps always undefined.

            Sentry.configureScope((scope) => {
                scope.setUser({ "id": store.user.id, "email": store.user.email }); // always undefined!
            });

Have I to update the scope every time a user logs in/out??

Thanks!
