How to display fields in Lists that are not being fetched by default

[hco]

Hi there,

I do have a list and want to display an additional field. For example, I do have a one-to-many reference and want to display it's count.

I tried

<NumberField source="targetItemsByTargetId.totalCount" />

From what I understand, the required field is not being added to the GraphQL-Query.
I wondered if this was because createQueryFromType skips fields that contain arguments, and the reference is paginated and thus has arguments?

Do I need to write a manual query for this?
I did not manage to find information on how I could do this together with ra-postgraphile, though :/

Sorry if this is a stupid question - it's my first time actually playing with React Admin.

Found it by myself - this needs to be a <ReferenceManyCount /> in my case.
