Strawberry Graphql does not allow extension by plugins

[129828]

Deployment Type

Self-hosted

NetBox Version

v4.0.9

Python Version

3.10

Steps to Reproduce

In versions before V4 it was possible to extend the graphql api using plugins:
For example a plugin that added EVPN data was able to be queried from the vlan:

{
  vlan_list{
    vid
    evpnvcvlan{
      evpn_vc {
      	vni
      }
    }
  }
}

This was done in the plugin itself and allowed to easily create links back and forth.

For example from a publicly available plugin, the netbox-bgp previously had this behaviour where it was possible to use graphql to query nested data.:

{
 device_list{
    bgpsession_set{
    	name
    }
  }
}

But in V4

{
 device_list{
    bgpsession_set{} <-- Yields an error
  }
}

And looking through the documentation of the strawberry api, I cannot seem to find a way to reenable this functionality.
The only option would be to first get all devices and then all bgpsession which have the device assigned, but the whole point of graphql is to only do a single request.

Expected Behavior

In version 4 it should still be possible to query the graphql api by using nested data from plugins, as right now it's only possible to do this using the netbox provided models.

Observed Behavior

It is not possible to use graphql to query nested plugin data
