Is it possible to add custom global functions to Luau runtime for websites

[xNasuni]

I'm using Luau.Web.js on a web page and I want to add a global function that exists in the runtime of the code, and I also want to be able to export data from there so I could do something like below:

function ExternalExport(data) {
    console.log(data) // {someVar: someValue}
}

And somehow run that function through luau, like this:

local someData = {someVar = "someValue"}
_G.ExternalExport(someData)

Like how @vegorov-rbx said in #1142, "No need to worry though, embedders of Luau can add any custom C functions to the global environment that they need in their applications, they don't have to be available in default configuration." but for JavaScript instead of C.

Extra information: I was using ceifa/wasmoon previously and it worked great but it was only Lua, and not Luau and I specifically need to run Luau and not normal lua.
I can also use NodeJS instead of websites if needed, or code something in C/C++ to use with WASM if possible.
