ResourceGuesser does not display referenced data suggestions for ManyToOne relations

[Gamesh]

Package versions

• api-platform/core: v2.6.8
• api-platform/schema-generator: v4.0.1
• @api-platform/admin: v2.8.3

Description
Can't get ManyToOne fields to work. All automatically rendered fields seems to have empty selections. Tried manually overriding the CreateGuesser but it also does not display any suggestions. It just does not seems to render any suggestions even through the response returns data

How to reproduce

Admin List

<React.StrictMode>
    <HydraAdmin entrypoint="/api">
      <ResourceGuesser name="warehouse_parts" create={WarehouseParts} />
    </HydraAdmin>
  </React.StrictMode>

Warehouse part create guesser

const WarehouseParts = (props: any) => (
  <CreateGuesser {...props}>
    <InputGuesser source="part"/>
  </CreateGuesser>
)

Looks like this for other relations as well even if i don't change anything and only use ResourceGuesser with no customisations

Ah it appears that if you don't expose a relation as a resource then you can't create relations or use that resource for autocomplete. So the solution here was to add <ResourceGuesser name="parts" />

which kind of sucks as you can't selectively expose only a subset of resources. It's all or nothing, defeats the purpose of customizing

Instead of a ResourceGuesser, you can just add a <Resource ...> imported from react-admin. React-admin, used for the amin interface, requires a Resource to be present for things like related inputs to work. But a <Resource ..> that does not have an edit/create/list prop, will not display in the menu. See https://marmelab.com/react-admin/doc/3.19/Inputs.html#reference-inputs
