How to make the bot react when they put a reaction on a message?

Question

Bots

I need the bot to respond to a given reaction to a message in a channel by pinging a specific role in another. Important: my bot is configured to set reactions to all new messages in a certain channel, and now it should react to the set reactions in the messages of this channel, but it is desirable that only 1 clicked, i.e. the one who clicked 1. Don't ask why I do this.

If you need to perform an action on a specific reaction, then you can do as below, but keep in mind that this is a method for cogs, if you do not have cogs, then redo it for yourself:

@commands.command()
async def command_name(self, ctx):
    channel = self.bot.get_channel(channel_id) # берем id чата
    message = await channel.fetch_message(message_id) #получаем все о сообщении по его id
    resactions = [reaction for reaction in message.reactions if reaction.emoji in ['иконка реакции1', 'иконка реакции2', 'иконка реакции3']]
    for reaction in resactions:
        if reaction.emoji == 'иконка реакции1':
             print("нажата реакция 'город'")
       elif reaction.emoji == 'иконка реакции2':
           # do your task...
