at.js via Google Tag Manager?

Has anyone had any success in deploying an at.js 2.x.x file via Google Tag Manager?

Could you share what challenge you have faced?

When I go to preview the 2.1.0 or 2.1.1 files in Google Tag Manager, the below error is being thrown:

I am able to successfully deploy 1.7, however we want to be able to take advantage of the visual editor on our SPAs, so it isn't exactly an option.

Isn't this because GTM doesn't support ES6?

I do get the same error which prevents GTM from publishing.
