The parameter to pass is chat_id but the attributes to use is chat_ids, Kinda confusing, see https://t.me/pythontelegrambotgroup/350760 https://github.com/python-telegram-bot/python-telegram-bot/blob/2789fd2bffe761e362c8dd115254b7c730fb9e35/telegram/ext/filters.py#L1234 vs https://github.com/python-telegram-bot/python-telegram-bot/blob/2789fd2bffe761e362c8dd115254b7c730fb9e35/telegram/ext/filters.py#L1241 would be good to align those.
