How to trigger a pop-up for a custom module via the IPC?

[postsolar]

I have the following widget:

  bindmode-with-hints = {
    type = "custom";
    bar = [
      {
        type = "bindmode";
      }
    ];
    popup = [
      {
        type = "label";
        label = "#bindmode"; # to be set to some multiline text at certain events
      }
    ];
  };

I want to toggle the popup via the IPC at certain events (bindmode change), but from the wiki page it's not apparent how to do so or whether it's possible at all. I tried this:

$ ironbar bar hyprbar show-popup custom
error
Module has no popup functionality

This should definitely be possible. Try adding a name property to the custom module, and use that to target it instead. If it still doesn't work, open an issue and I'll see if I can get it fixed.
