There are many bots in Telegram, such as @ChannelAnalyticsBot, @TGStat_Bot and @junction_bot, which can collect data from any channel (even if you are not a channel administrator) - posts, number of subscribers, etc. they just need to pass the name of the channel, or make a repost in the bot. As far as I know, there is no such possibility in the Telegram API, no matter how much I searched and did not find, in what way can something like this be done? Those. get access to the data of the channel in Telegram through the bot?
