NumberFormatOptions interface is missing unit and unitDisplay properties.

[obber]

TypeScript Version: 3.8.3 and Nightly

Search Terms: NumberFormatOptions unit unitDisplay

Code

console.log(new Intl.NumberFormat('en', {
    style: 'unit',
    unit: 'kilobyte',
    unitDisplay: 'short',
}).format(1.5));

Expected behavior:

unit and unitDisplay should be usable for NumberFormatOptions.

Actual behavior:

Argument of type '{ style: string; unit: string; }' is not assignable to parameter of type 'NumberFormatOptions'.
  Object literal may only specify known properties, and 'unit' does not exist in type 'NumberFormatOptions'.
