More convenient way to get the type of a signal-store?

[PhilippMDoerner]

Is there any way to access the type of a store to have e.g. type-safe callbacks that can be passed to mutate the store type-safely?

Say for example in this conceptual example, where a store has many custom features with lots of complex fields:

export const MyStore = signalStore(
  ... way too many custom features ...
)

function patchMyStore(store: <What goes here for MyStore?>, someData: number){
  patchState(store, { someFieldOnMyStore: someData } ) //someFieldOnMyStore is ideally type-safe
}

How can I type store so that it has the type of MyStore etc. ?

typeof MyStore is not correct and after that I'm running out of ideas.
