What should I pay attention to when configuring esm?

[Riveer01]

Hello,
I use pm2+esm to start the project, but the following error occurs: "Parse is not defined".
Parse is a global object in the third-party package "parse-server".

const brand = await new Parse.Query('Brand').select('brandName').equalTo('objectId', brandId).first();

There is no need using import or require for Parse.Query.
What should I pay attention to when configuring esm?
The following is the relevant configuration to start esm in pm2:

"script": "index.js",
"node_args": "-r esm",
