Accessibility Text	`accessibilityText`	Text	Additional text to be announced by screen readers. Used only for accessibility; produces no visible change.

Usage considerations

Saving and displaying values and placeholders

Any nulls in the array passed to selected groups are not displayed.
The component always saves an array regardless of how many selections have been made.
Whether placeholder text clears on focus or input varies by device and browser.

Filtering and permissions

Both direct and indirect members (groups that are members of groups that are members of the filter group) are suggested. The filter group is never suggested.
The user viewing the picker must be allowed to view any groups passed to the value. Only groups that the viewing user has permissions to see appear in the suggestions list. When group filter is not null, the viewing user must have permission to view members of the filter group for any suggestions to be made.
