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

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?
