[kk-slider18]

Description:
Group tabs and Statement tabs currently announce only the button text, which may be unclear. Users might not understand, the problems user might face is like:

1. Users might not know what these letters and numbers represent.
2. Users might not know which group a statement belongs to.

Adding ARIA labels to provide context is recommended.
