How do I index into an array type in Typescript?

Let’s say there is a type

type Groceries = {
  totalCost: number;
  items: Array<{
    name: string;
    price: number;
  }>

And I want to index into the nested type of price
How can I achieve this?

Doing Groceries["items"]["price"] is throwing an error, I believe because it is an Array type. How can I index into the individual types defined in the Array type?

Tried indexing by doing Groceries["items"]["price"]
