I am looking for an answer to the question of how to return the display name that the user sets on the profile instead of on the server, using discord.py

@discord.app_commands.command(name="get_nicknames", description="xyz")
async def get_nicknames(self, interaction: discord.Interaction):
    await interaction.response.defer(ephemeral=True)
    
    member = interaction.user
    user = await self.bot.fetch_user(member.id)
    
    display_name = member.global_name

    embed = discord.Embed(title="Twoje pseudonimy", color=discord.Color.blue())
    embed.add_field(name="Wyświetlana nazwa", value=display_name, inline=False)

    await interaction.followup.send(embed=embed, ephemeral=True)
