Enable sandbox mode for all requests

[malimccalla]

I have the following file that handles my sendgrid set up.

import sgMail from '@sendgrid/mail';

const sendGridApiKey = process.env.SENDGRID_API_KEY;

if (!sendGridApiKey) {
  throw new Error('The sendgrid api key has not been set in the environment variables');
}

sgMail.setApiKey(sendGridApiKey);

export { sgMail };

After setting my api key I need to be able to do something like this to enable sandbox mode on all requests

sgMail.enableSandbox(process.env.NODE_ENV !== 'production')

The absolute best solution would be not having to add a line of code like that at all but be able to generate an api key specifically for sandbox mode (similar to how Stripe has test keys). I really don't want to use my live production key in staging and development environments. Thanks!
