    const eventCategory = await interaction.guild.channels.create({
        name: ":dagger: " + interaction.options.getString("event-name") + ":dagger:",
        type: ChannelType.GuildCategory,
        pemissionOverwrites: [
          {
            id: playerRole.id,
            allow: [PermissionFlagsBits.ViewChannel],
          },
          {
            id: organizerRole.id,
            allow: [PermissionFlagsBits.ViewChannel],
          },
          {
            id: interaction.guild.roles.everyone.id,
            deny: [PermissionFlagsBits.ViewChannel],
          },
        ],
      });
