How to use the @microsoft/recognizers-text-sequence.recognizeEmail function in @microsoft/recognizers-text-sequence

protected async onRecognize(context: TurnContext, state: any, options: PromptOptions): Promise> {
        const result: PromptRecognizerResult = { succeeded: false };
        const activity: Activity = context.activity;
        const utterance: string = activity.text;
        const locale: string = activity.locale || this.defaultLocale || 'en-us';
        const results = recognizers.recognizeEmail(utterance, locale);
        if (results.length > 0 && results[0].resolution != null) {
            try {
                result.succeeded = true;
                result.value = results[0].resolution.value;
            }
            catch(e) {
                console.log(e);
            }
        }
        return result;
    }
}

public async onTurn(context: TurnContext, next: () => Promise): Promise {
        if (context.activity.type === ActivityTypes.Message) {
            const emails: ModelResult[] = recognizeEmail(context.activity.text, this.defaultLocale);
            const emailEntities: string[] = [];
            if (emails.length > 0) {
                for (const i of emails) {
                    emailEntities.push(i.resolution.value);
                }
                context.turnState.set('emailEntities', emailEntities);
            }
        }
        await next();
    }
