Typescript asserting types if they have one property true or false [duplicate]

Question

I have the following function:

type Option = {
  map?: {
    lat: number,
    lng: number
  }
  location?: boolean
}

const foo = (option: Option) => {
  if (option.map) {
    return {
      lat: option.map.lat,
      lng: option.map.lng,
    }
  } 

  if (option.location) {
    return 'location'
  }
}

• if I call it with foo(), Typescript complains there should be 1 argument (as expected)
• if I call it with foo({}), Typescript does not complain
• I can call it with foo({ map: {lat: 1, lng: 1 }}) or foo({ location: true }) with no problems.

How can I tell typescript that the object HAS to have one of or map or location? So that foo({}) is not accepted?

The following question: is there a way to tell Typescript they are exclusive properties? Eg: if there's a map, there can't be a location and vice-versa?

Thanks a lot.

(I'm truly sorry if this is a duplicate. I can't even begin to think how to search this or what terms to use.)
