Hi! I am working with a CosMx dataset where spatial coordinates are originally defined per FOV. CosMx also provides coordinates transformed into a global coordinate system, which I use to visualize all FOVs belonging to a TMA core together.

I am plotting the cells with:

```python
sq.pl.spatial_scatter(
    sdata,
    spatial_key="global",
    shape=None,
    connectivity_key="global_connectivities",
)

```

This produces the warning:

```plaintext
WARNING: Please specify a valid `library_id` or set it permanently in `adata.uns['spatial']`

```

I am having trouble understanding why a `library_id` is needed in this case. I am using `shape=None` and only want to make a scatter plot in my custom global coordinate system, without plotting a tissue image, is `library_id` actually necessary here? How do I silence the warning?

Thanks!
