How to Add Accessibility Tags and Alt Text for Graphs Imported from Illustrator in InDesign 2024

[twinkletop]

Hi Does anyone know how to tag and add alt text for graphs (brought in as AI files) from illustrator please? The <figure> tag doesn't seem to come up in 'object export options'? Indesign v19.5 - 2024. Do i just leave it to automatically detect there is a figure there - and add alt text, as I would do with an image?

With the placed .AI file selected, click on Object menu > Object Export Options > Tagged PDF > Apply Tag: Based On Object> Actual Text Source: Custom (write some alt text)
