Clarification needed: Is UXP publicly available for Illustrator in 2026?

Hi Adobe team and community,

I'm developing a UXP plugin that currently supports Photoshop and InDesign, and I'd like to add Illustrator support.

The confusion:

The official UXP versions page (https://developer.adobe.com/xd/uxp/uxp/versions/) clearly lists Illustrator with UXP support:

• Illustrator 23.0 → UXP v5.5
• Illustrator 27.0 → UXP v6.3

However, various forum threads from 2024-2025 state that "UXP is not available in the released version of Illustrator" and that it requires beta access.

My questions:

1. Is UXP now publicly available for Illustrator (as of February 2026), or is it still beta-only?
2. If it's available, where can I find the Illustrator UXP API documentation? I can find docs for Photoshop (require('photoshop')) and InDesign (require('indesign')), but nothing for Illustrator (require('illustrator')).
3. Specifically, I need to place images into the active document. In InDesign I use app.activeDocument.place(). What's the equivalent API for
     Illustrator? Is it placedItems.add() like in ExtendScript?
4. Does Illustrator UXP have executeAsModal like Photoshop, or does it work differently?

Any clarification or links to documentation would be greatly appreciated.

Thanks!
