How to sync local changes during offline when the connection is re-established?

Thanks for making this library!

I've been trying out this library with this example.
And I've reached a point where during offline, the changes I made locally is not synced when the connection is re-established.
I can tell because the product id is not assigned if it is created offline.

I made sure syncLocal is true.

` final productsState = ref.products.watchAll(
syncLocal: true
); `

and I tried:

// this action only overwrites my local state with server state
`await ref.products.appwriteAdapter.findAll(syncLocal: true);`

How do I perform such action? Does this package provide this feature?
I do see there's a merge function, is that the one? Can you show me how it works?

Many thanks!
