title: PWA not sharing file with navigator.share, only dowload
body: <p>This is my code</p>
  <pre class="lang-js prettyprint-override"><code>    let f: any = XLSX.writeFile(wb, this.generarNombre(pedido.folio), {
            bookType: 'xlsx',
            type: 'array'
          })
      
          let data: Blob = new Blob([f], { type: EXCEL_TYPE })
          let file = new File([data], this.generarNombre(pedido.folio), {
            type: EXCEL_TYPE
          })
      
          let navigator = window.navigator as any
      
          return new Promise((resolve, reject) =&gt; {
            let data = {
              files: [file],
              title: this.generarNombre(pedido.folio),
              text: pedido.folio
            }
            if (navigator.canShare(data))
              navigator.share(data).then(result =&gt; resolve(result))
            else reject('No soportado por el dispositivo')
          })
        }
  </code></pre>
  <p>My application is a PWA and it is installed successfully in android, the problem is that instead of sharing with the native option of android it only downloads the file. How can i solve this?</p>
