How to call Go methods from a frontend page in Wails v3?

[haikuoyun]

In Wails v3, I am trying to load a remote webpage built with Vue 3. I installed the @wailsio/runtime package and attempted to call a Go method from the page like this:

<template>
</template>

<script setup>
import { Call } from "@wailsio/runtime";

console.log(Call.ByName("main.GreetService.Greet", "123456")); 
</script>

When using wails3 dev and loading a local frontend, it works fine, for example:

app.Window.NewWithOptions(application.WebviewWindowOptions{
    // ...
    URL: "/",
})

However, when loading a remote webpage, it doesn’t work, for example:

app.Window.NewWithOptions(application.WebviewWindowOptions{
    // ...
    URL: "http://192.168.0.150:8081/",
})

I don’t want to integrate the frontend directly into Wails. I want to develop them separately, have Wails load a remote URL, and expose some interfaces from Wails to the webpage, similar to window['go'] in Wails v2 or Electron’s contextBridge.

In Wails v3, how can I call Go methods from a frontend page running in remote mode?

Thank you!
