Vue3 use ref from third party package in setup script

I’m using Vue 3 for my project and need to get use a ref from a third-party ReCaptcha package during the submission of a form. The code does not recognize the ref name since I did not personally create this ref:

async function submitContact() {
  const token = await mrecaptcha.getToken();
...

'mrecaptcha' is not defined.

It’s used in the template like this:

<recaptcha v-if="isClient" ref="mrecaptcha" :site-key="siteKey" />

Usage can be found in the docs for this package here: https://www.npmjs.com/package/@appsbd/vue3-recaptcha

Answer

You need to create a ref in the script to get the element reference of recaptcha.

const mrecaptcha = ref(null)

Ex:

<script setup>
const mrecaptcha = ref(null)

onMounted(() => {
  console.log(mrecaptcha)
})
</script>
