[400 BOT_METHOD_INVALID] - The method can't be used by bots (caused by "messages.GetDialogs"

Thank you for the bot.
I'm trying to set it up by using a bot account. After entering the bot token in the first step, this is what I get from the trace.

Traceback (most recent call last):

pyrogram.errors.exceptions.bad_request_400.BotMethodInvalid: Telegram says: [400 BOT_METHOD_INVALID] - The method can't be used by bots (caused by "messages.GetDialogs")

I've tried using a user account and everything worked fine. Probably some telegram api changes caused this?

As the documentation suggests, the .get_dialogs() method is not usable by bots (docs).
I commented the two lines as it seems like the method call is doing nothing. (not really)

PyWardBot/app/main.py

Line 1208 in 2bbbe9a

for dialog in user.get_dialogs():

Now the bot starts up as expected. However, the method is_identical_to_last is using the get_chat_history api method that suffers the same issue of the first one (docs).

After disabling the "Duplicate text" option from the bot, it skips the method call and now everything seems to work as expected.
