Was checking this out yesterday for lighting, but I'll assume the same applies: if the join is inaccessible you need to do it with maintenance free fittings and junction box e.g. Wago. Sounds like you will be able to access the junction but probably good practice anyway. Not sure if you need to fix in to fire retardant MDF or anything like that.
