How to register a helper in Discourse?

Development

What would customHelper do? Can’t you just do something like this instead?

in your initializer

export default {
  initialize(container) {
    const user = container.lookup('current-user:main');
    Discourse.ajax("/some-url").then(result => user.set("isPartOfParticularGroup", true));
  }
}

and in your .hbs file

{{#if currentUser.isPartOfParticularGroup}}
   // your stuff
{{/if}
