I have a Tauri app sidecar written in Node.js, I use pkg to package the node app into an executable, the name of the sidecar is server-x86_64-pc-windows-msvc.exe.
I am able to use @tauri-apps/api/shell in the client side and execute the sidecar:

import { Command } from '@tauri-apps/api/shell';
const command = Command.sidecar('bin/server');
console.log(command)
command.on('close', data => {
    console.log(`command finished with code ${data.code} and signal ${data.signal}`)
});
const output = await command.execute();
console.log("???? ~ output:", output)

However, one of the packages I am using inside the node app (the sidecar) requires 3rd party executable and files, so when I am executing the command I am facing a node.js Error: Cannot find module 'C:snapshotdist/build/Release... error.
When I am executing server-x86_64-pc-windows-msvc.exe directly on my PC it works fine and there is no problem with requiring the 3rd party files.
