Hi @Luca_Lattarini - this might actually be a question for Experience Cloud forums, but you need to be a full system admin or a Developer for the product profile in your enterprise account to see this tab: https://helpx.adobe.com/au/enterprise/using/manage-developers.html
You also need to have created the API integration using your enterprise login. Adobe.io console can sometimes log you in under you personal account and you need to use the account switcher in the top right to select the enterprise account you want to create the API integration inside.
Once you have both of these you can just add the API integration to the Analytics Product profile
Also - there are no permissions required on the product profile for it to work with Triggers
Hope this helps
Cheers Darren
