For reference, this replicates the behavior from the Core API Adapter:

cosmos-sdk/types/module/core_module.go

Lines 137 to 145 in adb03ec

	func (c coreAppModuleBasicAdaptor) GetQueryCmd() *cobra.Command {
	if mod, ok := c.module.(interface {
	GetQueryCmd() *cobra.Command
	}); ok {
	return mod.GetQueryCmd()
	}
	return nil
	}
