I think that some of the methods on the accessor class (e.g. [here](https://github.com/xarray-contrib/xdggs/blob/a22be6b48837b2a1b90067e9fce69b7f4725dd70/xdggs/accessor.py#L99-L131)) are not documented in the docs? Happy to fix this if someone could confirm that I did not miss this and maybe point me in the right direction. On an additional note, is this something that can be checked via a CI check?
