I need to use MS OAuth2 code from Azure login using react-native-azure-auth. Only accessToken and rawIdToken are accessible. Solutions to get "code"?

Question

async authorize(options = {}) {
        const scope = new Scope(options.scope)

        const { clientId, client, agent } = this
        const {nonce, state, verifier} = await agent.generateRequestParams()

        let requestParams = {
            ...options,
            clientId,
            scope: scope.toString(),
            responseType: 'code' + (scope.toString().includes('openid') ? ' id_token': ''),
            response_mode: 'fragment', // 'query' is unsafe and not supported, the hash fragment is also default
            state: state,
            nonce: nonce,
            code_challenge_method: 'plain',
            code_challenge: verifier
        }
        const loginUrl = this.client.loginUrl(requestParams)

        let redirectUrl = await agent.openWeb(loginUrl, options.ephemeralSession)

        if (!redirectUrl || !redirectUrl.startsWith(client.redirectUri)) {
            throw new AuthError({
                json: {
                    error: 'aa.redirect_uri.not_expected',
                    error_description: `Expected ${client.redirectUri} but got ${redirectUrl}`
                },
                status: 0
            })
        }

        // Response is returned in hash, but we want to get parsed object
        // Query can be parsed, therefore lets replace hash sign with '?' mark
        redirectUrl = redirectUrl.replace('#','?') // replace only first one
        const urlHashParsed = url.parse(redirectUrl, true).query
        const {
            code,
            state: resultState,
            error
        } = urlHashParsed

        if (error) {
            throw new AuthError({json: urlHashParsed, status: 0})
        }

        if (resultState !== state) {
            throw new AuthError({
                json: {
                    error: 'aa.state.invalid',
                    error_description: 'Invalid state received in redirect url'
                },
                status: 0
            })
        }
        
        const tokenResponse = await client.exchange({
            code,
            scope: scope.toString(),
            code_verifier: verifier
        })

        if (tokenResponse.refreshToken) {
            this.client.cache.saveRefreshToken(tokenResponse)
        }
        if (tokenResponse.accessToken) {
            let accessToken = await this.client.cache.saveAccessToken(tokenResponse)
            return accessToken
        } else {
            // we have to have at least id_token in respose
            return new BaseTokenItem(tokenResponse, this.clientId)
        }
    }

This is the code from src/webauth/index.js from react-native-azure-auth.

I need to access the value of code which is destructured from urlHashParsed.

Please help, thanks in advance.

I tried to get the value using imports. But code is not exposed by default.

This is highly unlikely scenario of usage, but my API requires the OAuth2 token to work rather than the accessToken or the rawIdToken.
