Making a GRPC request from an auth0 action

I have a post-signup auth0 action. I’m trying to call my services GRPC endpoint from it.

In the hook I’m trying to use the libraries required for this
var grpc = require(“grpc/grpc-js@1.6.3”)
var protoLoader = require(“grpc/proto-loader”);
var _ = require(‘lodash’);

And I’m getting

  "code": "MODULE_NOT_FOUND",
  "message": "Cannot find module 'grpc/grpc-js@1.6.3'\nRequire stack:\n- /data/io/node16/21e8e754-1670-4109-a015-b6bab6891f28/webtask.js",
  "name": "Error"

This package is said to be supported. Can I require? - Search which node modules you can use in

Is there a supported way to make GRPC requests from an auth0 action?
