How does Modal Interaction group?

[ha-ves]

I have this nested slash command module that has a modal response with a ModalInteraction in it:

[Group(ServerCmd.Server, ServerCmd.ServerDesc)]
internal class GameServerDiscordModule : InteractionModuleBase<SocketInteractionContext> {
...
    [SlashCommand(ServerCmd.Add, ServerCmd.AddDesc)]
    internal async Task ServerAddCmd_Exec(...) {
        await Context.Interaction.RespondWithModalAsync<AddServerModal>(ServerCmd.AddModal + servername);
    }

    [ModalInteraction(ServerCmd.AddModal)]
    internal async Task ServerAddModal_Exec(AddServerModal modal) {
    ...
    }
...
}

Is this a correct usage of ModalInteraction? Because the ServerAddModal_Exec cannot capture the submitted Modal.
I assume because it's inside a group/module it has to have the prefix, right? how do i use it as customid for RespondWithModalAsync?

Add ignoreGroupNames: true to the ModalInteraction to ignore group names

This do capture the command, as with regex and wildcard, but i wanna know how the grouping works, especially if the custom-id is dynamically changed at runtime.

Interaction Service uses the delimiters in InteractionServiceConfig.InteractionCustomIdDelimiters to traverse the nested group structures. So you can assing that prop a value if you want to enable that behaviour. But what @cjbonn said should also work.

Is there any way to access that Property from a Command Task?

Ok. This answers my question but needs more explanation on how ModalInteraction works, especially when the docs has yet to mention separators/delimiters.

For any interaction with custom-id, it needs to be configured as such:

// Chosen delimiters
String[] delimits = new[] { '_' };

// Creates a InteractionServiceConfig with the delimiters
var interDelimits = new InteractionServiceConfig() { InteractionCustomIdDelimiters = delimits };
// When creating a InteractionService, also pass in the config
var BotInteraction = new InteractionService(discord: BotClient, config: interDelimits);

// Then when sending responses, use the delimiters
await Context.Interaction.RespondWithModalAsync<AddServerModal>(customid: ServerCmd.Server + delimits[0] + ServerCmd.AddModal);

The rest is covered in the docs
