You need to add it to the element's schema:

     element: {
        types: {
            firstname: {
                name: "firstname",
                label: 'Name',
                description: 'Person name input',
                icon: 'http://www.w3.org/2000/svg',
                category: 'fields',
                sections: 'text',
                //separators: 'text',
                schema: {
                    type: 'text',
                    label: 'Adınız',
                    rules: [
                      'required',
                      'min:3'
                    ],
                },
            },
        }
    }
