how to use vue-i18n in slots

[rkrater]

I'm trying to vue-i18n in the label slot for the form group component. Both blocks of code get TypeError: _vm.t is not a function. Does anyone know the correct way?

  <b-form-group>
	<template v-slot:label>
        <i18n path="5_304_thank_you_for_engaging_wi" tag="span">
          <template v-slot:date>
            <strong>{{ meeting.date_meeting_on }}</strong>
          </template>
        </i18n>
	</template>
	<b-input
	  name="email"
	  v-model="form.email"
	/>
  </b-form-group>

  <b-form-group>
	<template v-slot:label>
	  {{ $t('5_283_email_required')}}
	</template>
	<b-input
	  name="email"
	  v-model="form.email"
	/>
  </b-form-group>
