You’re not going to get an “accompanying” visa for a spouse in any consulate or embassy around this area. They stopped issuing those years ago. For a kid yes. I don’t know the specifics but their website should give details.
The only way these days to get a “piggyback” visa for a spouse is if the main visa holder applies for a Non OA visa in their home country - which requires a health check, police check and insurance. Then the embassy may issue a Non O to the spouse. Not all will.
