channel_post_handler does not see posts made by another bot

[robertpustota]

So I have this handler

@bot.channel_post_handler(func=lambda message: True, content_types=["text", "document", "photo", "audio", "video", "voice"])

That works well and would catch a message if I sent it, but when it sends another bot, for some reason, this handler does not catch a message.

Can It be that Telegram has forbidden communication with bots, even in channels?

Have no additional information. May be Telegram improve something at backend...
