Is it possible to work with a npm like otpauth?

Hello everyone.

I'm trying to build a 2FA system on VBCS and I was wandering if I could use the funcionalities of otpauth ( and others npms ) by referencing it on HTML like:

<script src="https://cdnjs.cloudflare.com/ajax/libs/otpauth/VERSION/otpauth.umd.min.js"></script>

If not, is there another way to use npms?

Thanks a lot in advance.
