Relation between custom modules and suitecrm modules

i created a custom module for accounts and added a relationship with the module “Contacts”
The module “Contact” was already defined in SuiteCRM.
I can see the panel contacts in the Edit view of my custom module but there is no contact there.
I noticed that the contacts that were in the Module “Contacts” only appear in the original Module account provided by SuiteCRM.
I hope my question can be understood

Can you kindly share some screenshots so we can better contribute solving your issue?

You can create a logic hook and create the actual relationship for your records.
