I want to switch to an app_commands.Group

[NavisGames]

When i have commands like these:

    @app_commands.command(name="loadcog", description="Loade einen cog")
    @app_commands.guilds(1003719600321597531)
    @commands.is_owner()
    async def loadcog(self, interaction: discord.Interaction, cog: str):
        await interaction.response.defer()
        try:
            await self.client.load_extension(cog)
            await self.client.tree.sync()
        except Exception as e:
            await interaction.followup.send(
                f"**cog konnte nicht loaded werden!**\n{e}", ephemeral=True
            )
            return
        await interaction.followup.send(f"cog loaded!", ephemeral=True)

#...

    @unloadcog.autocomplete("cog")
    @loadcog.autocomplete("cog")
    @reloadcog.autocomplete("cog")
    async def autocompletion(
        self, interaction: discord.Interaction, current: str
    ) -> typing.List[app_commands.Choice[str]]:
        try:
            data = []
            paths = [
                os.path.join(root, file)
                for root, dirs, files in os.walk("./cogs")
                for file in files
            ]
            for path in paths:
                if not path.endswith(".py"):
                    continue
                module_name = path[2:].replace("/", ".").replace(".py", "")
                data.append(
                    app_commands.Choice(
                        name=module_name,
                        value=module_name,
                    )
                )
            return data[:20]
        except Exception as e:
            print(f"Fehler beim COG Autocomplete: {e}")

how can i transfer it to an app_commands.group ?

the first things i already got are

    @app_commands.guilds(1003719600321597531)
    class OwnerCommands(app_commands.Group):
        pass
