Is it possible to conditionally get a property from a nested object?

[h2ck4u]

I'm writing in hopes of getting some help.

I would like to know if it is possible to have a scenario like this one:

interface Paths {
  '/api/pet': {
      'get' :{},
  },
  '/api/store': {
      'get' :{},
  },
  '/api/pet/{id}': {
     'post': {},
  },
  '/api/store/{id}': {
     'post': {},
  },
};

type Methods = 'get' | 'post' | 'put' | 'delete' ;


type PathKeysWithMethod<Paths, TMethod extends Methods> = SomeUtils<Paths, "Some condition here"> ;

const pathOfGetMethod: PathKeysWithMethod<'get', Paths>
// expect '/api/pet', '/api/store' 

const pathOfPostMethod: PathKeysWithMethod<'post', Paths>
// expect '/api/pet/{id}', '/api/store/{id}' 

i tried

type PathKeysWithMethod<Paths , TMethod extends Methods> = StringKeyOf<
  ConditionalPickDeep<Paths, Record<TMethod, unknown>>;

const pathOfPostMethod: PathKeysWithMethod<'post', Paths>

// result
'/api/pet', '/api/store', '/api/pet/{id}', '/api/store/{id}', 

//expected 
'/api/pet/{id}', '/api/store/{id}'
