Need to put validation to the tab

Hello team,

I have question that there are 2 tabs and inside it there is available 3 fields. For example, we have MainTab and AdditionalTab and inside MainTab there is firstname, lastname, middlename. Inside AdditionalTab there is Phonenumber, email, birthdate. I need to put validation to this fields separately. If I put validation to firstname and Phonenumber, these two shouldn't affect each other. when Firstname and Phonenumber is not filled in and try to save record, if I am on Maintab, system should return Firstname validation. at the same time, when I change tab to AdditionalTab, system should return Phonenumber validation. in this case how can I put validation based on tabs?

Below I'll share written code for validation.

               type: Terrasoft.ViewModelColumnType.VIRTUAL_COLUMN,
               value: "" // Initial value, empty by default
           }
       },

               }

           },
