[Vuejs]-Vuelidate make input field 1 or input field 2 required "Or" validator?

I now got it to work. The problem was that I used form:{} so I need to use this.form.phone or this.form.mobile to get the value.

export default {

mixins: [validationMixin],
data: () => ({
  form: {
    email: '',
    phone:'',
  },
}),

So to get it to work I have to use:

  validations: {

    form: {
      email:{
        required (v) {
        return this.form.phone|| required(v)
      }},

      phone: {
        required (v) {
          return this.form.email|| required(v)
      }},
   },
