Finding from the audit attached to Epic -this may have been done by the previous accessibility work, please confirm:

• In addition to headings, side areas offer a possibility for structural navigation
• If not all areas of the application are semantically marked as such, they cannot be accessed directly by screen reader or keyboard users (via browser add-on)
• The breadcrumb and the sidebar are to be marked as navigation areas with the element.
• To distinguish between the two navigation areas, a meaningful aria label must be assigned, which makes it clear which navigation area is involved. The main content area is to be marked with the element.
