Discord.py - Optional Args

I'm having trouble setting up a command with an optional Arg to reload my cogs. It was telling me the command didn't exist and after some modifications it was reloading all of the arguments even when I use an arg for a specific cog. Currently it's trying to reload a cog called None.

My Code:

@commands.has_role("Founder")
@bot.command()
async def reload(ctx, extension=None):
    if  ctx.channel.name == ("dev-testing") and {extension} == None:
        for filename in os.listdir('./cogs'):
            if filename.endswith('.py'):
                bot.unload_extension(f'cogs.{filename[:-3]}')
                bot.load_extension(f'cogs.{filename[:-3]}')
                await ctx.send("All cogs have been reloaded!")
                print(bcolors.WARNING + "All cogs have been reloaded!" + bcolors.ENDC)
        

    elif ctx.channel.name == ("dev-testing") and {extension} != None:
            bot.unload_extension(f'cogs.{extension}')
            bot.load_extension(f'cogs.{extension}')
            await ctx.send(f'{extension} has been reloaded!')
            print(bcolors.WARNING + f'{extension} has been reloaded!' + bcolors.ENDC)

And this is the error I get when I don't specify an arg.

discord.ext.commands.errors.ExtensionNotLoaded: Extension 'cogs.None' has not been loaded.

I have made multiple modifications to this trying to get it to work and it's still trying to load the default value for the arg. I even tried without a default value, I tried with NULL, I tried all kinds of things but can't seem to get this working properly.

Any help would be appreciated.

Why are you comparing it like this?

if {extension} != None:

When putting it inside the curly brackets you're casting it to a set, a set is never None, simply do:

if extension is not None:
