When CI job is complete execute another job

We have multiple stages in our pipeline that needs to be executed in order:

build (does a build & test)
publish (publishes artifacts to nexus)
container (creates a docker container)
dev (deploys container to our development env)
qa (deploys container to qa env)
prod (deploys container to prod env)
update_dependencies (runs a program that finds all services that depend on my client and create merge request for the new version)

build, publish, container, dev are all automatic

qa, prod are manual

update_dependencies should run after prod has been successfully executed

I need a way to have prod execute update_dependencies after a successful run of the prod job.

A new config setting for a job to look something like:

prod: <<: *deploy_definition stage: prod when: manual environment: prod

update_dependencies: <<: *update_dependencies_definition when: on_success: prod

When prod job has been successfully completed, it will start update_dependencies job.
