Role issuance system - bots

Question

There is a command to request a role. I don't understand how to set some functions for reactions.
#client.command()
async def role(ctx):
role = ctx.guild.get_role(703596629860548643)
zapros_chanell = client.get_channel(729733881129074768 )
zapros2_chanell = client.get_channel(703596629923725339 )
embed = discord.Embed(title="Запрос роли")
embed.add_field(name='Запросивший роль', value=ctx.message.author.mention)
embed.add_field(name='Роль для выдачи', value=role.mention)
embed.set_thumbnail(url=ctx.guild.icon_url)
message = await zapros_chanell.send(embed=embed)
await zapros2_chanell.send(embed = discord.Embed(description = f'{ctx.message.author.mention}, `запрос на выдачу роли был успешно отправлен, ожидайте его рассмотрения модерацией Discord`', color=discord.Color.purple()))
await message.add_reaction('✅')
await message.add_reaction('❎')
The bottom line is that if when you click on ✅, the role was issued and a text was written to the person in zapros2_chanell.
When you click on ❎, the person was not given a role, therefore, but a certain text was also written in zapros2_chanell.

Answer 1

I used an event called on_raw_reaction_add. Made a check to the reaction, keep in mind the will give the role to any message in the guild with ✅.It it just a proof of concept.
You can make it only accept reactions on certain channel, or even only for given message IDs
#client.command()
async def role(ctx):
zapros_chanell = client.get_channel(729733881129074768)
embed = discord.Embed(title="Запрос роли")
embed.add_field(name='Запросивший роль', value=ctx.message.author.mention)
embed.add_field(name='Роль для выдачи', value=role.mention)
embed.set_thumbnail(url=ctx.guild.icon_url)
message = await zapros_chanell.send(embed=embed)
await zapros2_chanell.send(embed = discord.Embed(description = f'{ctx.message.author.mention}, `запрос на выдачу роли был успешно отправлен, ожидайте его рассмотрения модерацией Discord`', color=discord.Color.purple()))
await message.add_reaction('✅')
await message.add_reaction('❎')
#client.event
async def on_raw_reaction_add(payload):
channel = await client.fetch_channel(payload.channel_id)
message = await channel.fetch_message(payload.message_id)
user = await client.fetch_user(payload.user_id)
emoji = payload.emoji.name
guild = client.get_guild(ID_HERE)
role = guild.get_role(703596629860548643)
zapros2_chanell = client.get_channel(703596629923725339 )
if user.id != bot.user.id: # bot to count itself
if emoji == '✅':
await client.add_roles(user, role)
await zapros2_chanell.send(f'{user.name} has been given {role.name}')
elif emoji == '❎':
await zapros2_chanell.send(f'{user.name} did not want {role.name}')
