Does Signal Stores have something similar to ngrx/effects ?

I am finally taking a look at Signal Store and I am not able to find a way to replicate an "open subscription" like the one that is possible with ngrx/effects.

Use Case, An angular app running in an android device, that listens to Android side events to update a local store.

How do I "subscribe" (or put a callback) to an someWindowObjectThatConnectsToNativeSide.addEventlistener('my-event') and then can update the current SignalStore?

Cheers and thanks!

Edit: I think this is the one that does one to one what I wanted https://www.reddit.com/r/Angular2/comments/1iiaul7/comment/mb4ds0j/
