Type Helper to select fields

Hello there ! A picture is worth a thousands words. I'm trying to write this helper, but it breaks inference. Does anyone know of something that could work ?

export type Select<T> = {
  [P in keyof T]?: boolean;
};

export type Select<T> = {
  [P in keyof T]?: boolean;
};

any news about the solution for this?

The problem here is that there is no connection between the Select helper and the columns type Typescript is not able to bridge the connection there, typescript just sees that Select is some Record<string, boolean>
