[Telegram, event pipeline, .Net] Most events do not run #6679
Description
Version
Microsoft.Bot.Builder 4.22.2
Describe the bug
I’m working with a Telegram bot and want to capture events when a user blocks the bot or starts a new conversation. With Web Chat, everything works fine, but Telegram doesn’t seem to trigger these events.
Is this the expected behavior, or does the Bot Framework not support these events for Telegram bots? I couldn’t find any official information about this limitation.
