Textinputs not working when I implemented "Unity webGL" in VueJS Project

I'm doing in my work educational curses with VueJS, when I export Unity resources, the text inputs and text area, are not working.

The call:

  <unity src="UnityResources/Build/cubito.json" width="600" height="400" unityLoader="UnityResources/Build/UnityLoader.js" ref="myInstance"></unity>

The component:

     Vue.component('unity', {
         template:`
               <div class="webgl-content">
                 <div id="unity-container" v-bind:style="{ width: width + 'px', height: height + 'px' }"></div>
                 <div v-if="loaded == false">
                   <div class="unity-loader">
                     <div class="bar">
                       <div class="fill" v-bind:style="{ width: progress * 100 + '%'}"></div>
                     </div>
                   </div>
                 </div>
                 <div class="footer" v-if="hideFooter !== true">
                   <a class="fullscreen" @click.prevent="fullscreen">Fullscreen</a>
                 </div>
               </div>
