Document Bot and Conversations chat IDs

[PaulCombal]

I have a doubt about the way chat IDs are handled in Nutgram, for which I could not find an answer.

I created an inline menu, the running method is polling, here is a snippet of a handler's code:

public function handler(Nutgram $bot) {
...
            echo "==========\n";
            echo "BOT CHAT ID: " . $bot->chatId() . "\n";
            echo "CONV CHAT ID: " . $this->getChatId() . "\n";
            echo "==========\n";

BOT CHAT ID: 5502227XXX
CONV CHAT ID:

What's the difference between the Bot Chat ID and the Conversation Chat ID?

How come the bot holds the chat ID and the InlineMenu holds NULL?

When does an InlineMenu hold a Chat ID?

Will the bot always be reliable with Chat IDs with multiple concurrent users?

According to this documentation: https://nutgram.dev/docs/usage/conversations#starting-a-conversation-from-server-side , I should be able to retrieve the chat ID from $this since InlineMenu extends Conversation

I am a bit inexperienced with the Telegram API, and this is the kind of moment I wish the documentation would be a bit beefier around these details. Instinctively, it would make more sense to me if the conversation held the chat Id with the user. I need to understand why this was not implemented this way.

Let me know if you need any more details

Thank you for your amazing work
