iconType for navigation items (group/anchor/...)

[snmkl]

Currently it is possible to set iconType on a page's frontmatter, and this is reflected as expected on the sidebar.

However, there doesn't seem to be possibility to set iconType on a "group", "anchor" or other navigation items that do have an "icon" field. This prevents customizing the sidebar fully.

(The mintlify bot seems to hallucinate this possibility).

Is this expected or a missing feature/bug here? Didn't want to create an issue immediately.

Thank you!
