So I have a custom object which main association is with a company, let’s call is licences.
When a contact submits a ticket, I would like the licence object to show on my side bar so customer support team knows what level of service that customer will receive.
Considering what level we have to contract to access custom object it should be able to do everything!

Hi @MChenery
Custom objects will only show / be available in the right hand column of an object record if the custom object is set to be associated with the record.
See my example below, in my custom objects settings I am setting an association with a ticket.
That means the association is then available in the right hand column and will show.
Records customisation settings
Object record with association
Depending on how you associate the the license object to the company, you need to figure out a way to carry the company → custom object association into the ticket.
