Integration with Azure Devops Repository

Hello, I am trying to connect my Postman API to an Azure Devops repository, however I get the message saying that I have reached maximum limit of API Git integrations. I have no previous integrations, so I don’t know why I am getting this message? I tried using a Basic plan trial to see if it would help but I still get the same message.

Would be great with some guidance!
Kind Regards Ida
