Typescript nested populate types?

[SupertigerDev]

export interface Friend {
  blocked: boolean
}
const FriendSchema = new Schema<Friend>({
  blocked: Boolean
})
const Friends = model<Friend>("friends", FriendSchema);


export interface User {
  friends: Types.ObjectId[];
}
const UserSchema = new Schema<User>({
  friends: [{ type: Schema.Types.ObjectId, ref: 'friends' }]
})
const Users = model<User>("friends", UserSchema);


Users.findOne({}).populate<{friends: Friend[]}>('friends').then(user => {
  user?.friends[0].blocked // works
  user?.friends.map(friend => friend.blocked) // Property 'blocked' does not exist on type 'ObjectId'.ts(2339)
})

how do i fix this typescript issue? When using map I get the error Property 'blocked' does not exist on type 'ObjectId'.ts(2339).
