Deprecated config options

[Cameron485]

We are using the SaaS hosted Flagsmith within our NextJS application and I have bumped Flagsmith to version 8 and some of the config options appear to be deprecated but the new types don't appear to be correct. Below is an example of our Flagsmith setup which does work, but the lack of typing or updated docs makes think we should be using the previously deprecated options.

'use client';

import { useEffect, useRef } from 'react';
import { FlagsmithProvider, useFlagsmith } from 'flagsmith/react';
import { createFlagsmithInstance } from 'flagsmith/isomorphic';
import useAuth from '../../hooks/useAuth';
import { getFlagsmithTraits } from '../../utils/auth';

const FlagsmithUserIdentifier = () => {
    const flagsmith = useFlagsmith();
    const { isLoggedIn, userId, user } = useAuth();

    useEffect(() => {
        const identifyUser = async () => {
            try {
                await flagsmith.setContext({
                    identity: {
                        // not typed
                        identifier: isLoggedIn ? userId : null,
                        traits: isLoggedIn ? getFlagsmithTraits(user) : null,
                    },
                });
            } catch (e) {
                console.log(e);
            }
        };

        identifyUser();
    }, [flagsmith, isLoggedIn, userId, user]);

    return null;
};

const TestFlagsmithProvider = ({ children }: { children: React.ReactElement }) => {
    const flagsmithRef = useRef(createFlagsmithInstance());
    const { isLoggedIn, userId, user } = useAuth();
    return (
        <FlagsmithProvider
            options={{
                evaluationContext: {
                    identity: {
                        traits: isLoggedIn ? getFlagsmithTraits(user) : {},
                        // not typed
                        identifier: isLoggedIn ? userId : null,
                    },
                    // not typed
                    environment: {
                        apiKey: process.env.NEXT_PUBLIC_FLAGSMITH_ENVIRONMENT_ID || '',
                    },
                },
            }}
            flagsmith={flagsmithRef.current}
        >
            <FlagsmithUserIdentifier />
            {children}
        </FlagsmithProvider>
    );
};

export default TestFlagsmithProvider;
