Using `[SlashCommandGroup]` appears to be non-functional

[VelvetToroyashi]

Attempting to mark a class a group, and putting methods inside that class registers them as top-level commands instead of group commands.

    [SlashCommandGroup("test", "Testing!")]
    public class Test : SlashCommandModule
    {
        [SlashCommandGroup("testing", "aaaaa")]
        public class Test2 : SlashCommandModule
        {
            [SlashCommand("aaaa", "aaaa, but 1")]
            public Task A(InteractionContext ctx) => ctx.CreateResponseAsync(InteractionResponseType.ChannelMessageWithSource, new() {Content = "A", IsEphemeral = true});

            [SlashCommand("bbbb", "aaaa, but 1")]
            public Task B(InteractionContext ctx) => ctx.CreateResponseAsync(InteractionResponseType.ChannelMessageWithSource, new() {Content = "B", IsEphemeral = true});

            [SlashCommand("cccc", "aaaa, but 1")]
            public Task C(InteractionContext ctx) => ctx.CreateResponseAsync(InteractionResponseType.ChannelMessageWithSource, new() {Content = "C", IsEphemeral = true});

        }
    }

Registers them properly But doing something like:

Registers them as top-level commands

This is all based on what's advised in the readme

This is a known issue/intended behaviour. You're supposed to create a group inside your main command class, marking the command class as a group does nothing. You should be doing

public class GroupedCommands : SlashCommandModule
{
    [SlashCommandGroup("test", "Testing!")]
    public class Test : SlashCommandModule
    {
        [SlashCommandGroup("testing", "aaaaa")]
        public class Test2 : SlashCommandModule
        {
            [SlashCommand("aaaa", "aaaa, but 1")]
            public Task A(InteractionContext ctx) => ctx.CreateResponseAsync(InteractionResponseType.ChannelMessageWithSource, new() {Content = "A", IsEphemeral = true});

            [SlashCommand("bbbb", "aaaa, but 1")]
            public Task B(InteractionContext ctx) => ctx.CreateResponseAsync(InteractionResponseType.ChannelMessageWithSource, new() {Content = "B", IsEphemeral = true});

            [SlashCommand("cccc", "aaaa, but 1")]
            public Task C(InteractionContext ctx) => ctx.CreateResponseAsync(InteractionResponseType.ChannelMessageWithSource, new() {Content = "C", IsEphemeral = true});

        }
    }
}

Requiring a nested type for make a slash command group is a bit...cumbersome.

Especially when all you want is a group
