Text is added as aria-label tag. Note - not all screen readers and browsers support this.

tabIndex

Number

In case you set it to some number, the map will set focus on lines (one by one) when user clicks tab key. When a focus is set, screen readers like NVDA Screen reader will read label which is set using accessibleLabel property of LinesSettings or individual line. If area is clickable, pressing Enter/Return while focus is set will select the line. Note, not all browsers and readers support this.
