Can I create a TG bot that acts just as a callback handler?

[fomotrader]

Here's a proof of concept I'm trying to build, I have a telegram bot that sends http requests to TG. Those requests contain an inline keyboard button with callback_data. When I click on that button I'd like to listen for updates using teleoxide and handle those updates. But I've struggled with using teleoxide without defining the different states a bot can be in. Can someone help me figure out where I'm going wrong. I'm still not proficient with Rustlang, it's a bit complex.

use teloxide::{
    dispatching::{dialogue, dialogue::InMemStorage, UpdateHandler},
    prelude::*,
};

type MyDialogue = Dialogue<State, InMemStorage<State>>;
type HandlerResult = Result<(), Box<dyn std::error::Error + Send + Sync>>;

#[derive(Clone, Default)]
pub struct State;

#[tokio::main]
async fn main() {
    pretty_env_logger::init();
    log::info!("Starting bot...");

    let bot = Bot::from_env();

    Dispatcher::builder(bot, schema())
        .dependencies(dptree::deps![InMemStorage::<State>::new()])
        .enable_ctrlc_handler()
        .build()
        .dispatch()
        .await;
}

fn schema() -> UpdateHandler<Box<dyn std::error::Error + Send + Sync + 'static>> {
    // use dptree::case;

    let callback_query_handler =
        Update::filter_callback_query().branch(dptree::endpoint(receive_callback));

    dialogue::enter::<Update, InMemStorage<State>, State, _>().branch(callback_query_handler)
}

async fn receive_callback(
    _bot: Bot,
    _dialogue: MyDialogue,
    _msg: Message,
    q: CallbackQuery,
) -> HandlerResult {
    println!("Received a callback");
    if let Some(callback_data) = q.data {
        if callback_data == "product" {
            println!("Received callback for 'product'");
        }
    }

    Ok(())
}

I get this stack trace and I've been stuck trying to fix this for a long time.

teloxide_core::types::message::Message was requested, but not provided. Available types:
    teloxide_core::types::me::Me
    teloxide::dispatching::dialogue::Dialogue<midman::State, teloxide::dispatching::dialogue::storage::in_mem_storage::InMemStorage<midman::State>>
    alloc::sync::Arc<teloxide::dispatching::dialogue::storage::in_mem_storage::InMemStorage<midman::State>>
    midman::State
    teloxide_core::types::callback_query::CallbackQuery
    teloxide_core::bot::Bot
    teloxide_core::types::update::Update

You need to remove _msg: Message, parameter from receive_callback.

You either receive a Message or a CallbackQuery not both at the same time.

Since you indicated filter_callback_query, this becomes a CallbackQuery handler, not a Message handler.
