[Python] Cannot send messages to group chat using Discord.py

This is my current code: Every time I get a group chat's recipients, it returns an empty array. I also have tried sending messages to group chats, and all of the sorts. I have already handled Intents, so that's not the problem.

import os
from random import choice
from discord import Client, Intents, Interaction, app_commands, ChannelType

intents = Intents().all()

app = Client(intents=intents)
tree = app_commands.CommandTree(client=app,
allowed_contexts=app_commands.AppCommandContext(guild=True, dm_channel=True, private_channel=True),
allowed_installs=app_commands.AppInstallationType(guild=True, user=True))


@app.event
async def on_ready():
print(await tree.sync())
if not app.user:
raise Exception("Wrong.")
print(f"logged in as {app.user.name}")


@tree.command(name="someone")
@app_commands.private_channel_only()
async def someone(interaction: Interaction):
channel = interaction.channel
if channel is None:
return
members = None
match channel.type:
case ChannelType.group:
members = channel.recipients
case ChannelType.private:
members = channel.recipients
case ChannelType.text:
members = channel.guild.members
case _:
return
got = choice(members)
await interaction.response.send_message(got.mention)


app.run(os.environ['key'])

The above exception was the direct cause of the following exception:

This is the traceback, if you are interested.
