ReferenceError: Buffer is not defined

[VisionaryAppDev]

I tried to use this package in my Sveltekit project and got Buffer is not defined.

Here is my code:

  import FlakeId from "flake-idgen";
  import intformat from "biguint-format";

  const flakeIdGen = new FlakeId();
  let id = intformat(flakeIdGen.next(), "dec");

Here is my error log:

Not sure if this package will work in a Jamstack project.
