Typescript. How to get enum item data as a type

I have an enum type, for example Currency. I cant to change it because it automatically builds on a graphql schema. I want to use it for my data, but I dont know how to do.

enum Currency {
  rub = 'RUB',
  usd = 'USD',
  eur = 'EUR',
}

const data: { currency: Currency[keyof typeof Currency] } = {
  currency: 'RUB',
};

Errors

TS2339: Property 'eur' does not exist on type 'Currency'.
TS2339: Property 'rub' does not exist on type 'Currency'.
TS2339: Property 'usd' does not exist on type 'Currency'.

I'm not sure it's possible to do exactly what you're trying to do but most likely, you'd want to do something like this:

const data: { currency: Currency } = {
  currency: Currency.rub,
};

This is how enums are typically used (by always explicitly referencing the enum when getting one of its values).
