Actual Results

When the user is added/ removed from the data table, the feedback message is not conveyed to the screen reader users. Thus screen reader users are not aware about the action performed.

Expected Results

The screen reader should announce the feedback message for their users.

Use ARIA live region to make sure that the dynamic update is announced for screen reader users. This can be achieved by either adding a live region role="status" or  aria-live="polite" and aria-atomic="true" attributes.

The message can be for example

"Test123 user added" or "Test123 user removed".

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
