How To create binding to object.object.function? (gapi.auth2.getAuthInstance)

I have this code in js:

function signInWithGoogle() {
    const auth2 = gapi.auth2.getAuthInstance();
    auth2.signIn().then(function(googleUser) {
        // Usa getAuthResponse() para obtener el token de acceso, ID, etc.
        const authResponse = googleUser.getAuthResponse();
        console.log('Access token:', authResponse.access_token);
        console.log('ID token:', authResponse.id_token);
    }, function(error) {
        console.error('Error during sign-in:', error);
    });
}

But I want to develop it entirely in Rust. How do I do this in wasm-bindgen?

Assuming that gapi is a global variable, you can use js_namespace to do that:

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
extern "C" {
    type Auth2;

    #[wasm_bindgen(js_namespace = ["gapi", "auth2"], js_name = "getAuthInstance")]
    fn get_auth_instance() -> Auth2;
}

Calling get_auth_instance will then call gapi.auth2.getAuthInstance().
