Settings Record to reference a database connection

Module Development
1

For a module I try in a record to reference a database connection.
What is the @FormField annotation to use ?
FormFieldType.REFERENCE or FormFieldType.SELECT or other ?

public record MySettingsResource(
        @FormCategory("MyCategory")
        @FormField(FormFieldType.REFERENCE)
        @Label("Db connection")
        @Required
        @DefaultValue(???)
        @Description("DB connection to use")
        String dbConnection ???
)
{
...

@FormField + @FormRerefenceType.

Example from BACnet:

@FormField(FormFieldType.REFERENCE)
@FormReferenceType("com.inductiveautomation.opcua.drivers.bacnet/BacnetIpLocalDeviceConfig")

where the reference type is the fully-qualified path to the type of reference (module id + resource type id). In your case ignition/database-connection I think?
