Hello,

I'm working with Odoo 18 enterprise and have installed the partner_multi_relation module from the OCA repository. This module allows flexible management of relationships between contacts and adds a smart button called "Relations" in the contact form view, which opens a view listing those relations.

What I would like to do is to extend or customize this behavior so that the relationships are displayed in a notebook tab directly within the contact form, instead of relying solely on the smart button.

I'm planning to create a custom module to achieve this. Could anyone guide me on how to do this or point me to a similar existing implementation? Any example or suggestions on how to extend the contact form view to include this relationship list would be greatly appreciated.

Thanks in advance for your help!
