Cannot make Koffi (npm) work with its module after compile

Hello, I wanted to try reading dll with Koffi but when it's compiled, it doesn't work because it need to access its module. I tried to include them with --include like the Koffi's documentation said https://koffi.dev/packaging but I didn't manage to make it work. I don't know if the issues is from Koffi, Deno or me being a completely idiot... You can easily test it with this code

import koffi from "npm:koffi";
console.log(koffi.config());

import koffi from "npm:koffi";
console.log(koffi.config());

Then compile

deno compile -A main.ts

deno compile -A main.ts

And run it. You should have the error

error: Uncaught (in promise) Error: Cannot find the native Koffi module; did you bundle it correctly?

Try to use node-opcua-client (npm) with Deno but struggle

Hello, I want to try to migrate a little app to Deno because the compile option suit my need and that now it support npm package. I want to use the npm package node-opcua-client but I've got this error message

NodeOPCUA creates automatically a default certificate when a client is first started. But my guess is either the symlink deno create for node_modules cause the issues or a permission missing but I already run the project using -A. I don't have this with Node Can you help me troubleshooting this ?
