Capacitor 3 and VueJS, open saved file (or download) - vue.js

Question

I am struggling with something I thought will be simple.
Ideally I want to save my base64 file with prompt same as you get when downloading from browser, however that seems impossible with capacitor app.
So I used FileSystem, to save file on Documents directory, which went fine, I also can get uri file. But because there is no indicator that file was saved, I would like to at least try to open the file with native apps. I've noticed there is cordova plugin cordova-plugin-file-opener2 but I can't seem to make it work with capacitor 3 and VueJs, without cordova.
Maybe I am overthinking it ? is there any way download file or open file with Capacitor?
For web view (not native app) I am using hidden download button, but that does not work at all in capacitor app
here is my current code
Filesystem.writeFile({
data: pdf,
path: `${this.fileName}.pdf`,
directory: Directory.Documents,
}).then(() => {
Filesystem.getUri({
path: `${this.fileName}.pdf`,
directory: Directory.Documents,
}).then(res => {
// open file here with my res.uri ?
);
});

I had the exakt same problem. I solved/workarounded it by using the official capacitor "Share" plugin, so the user can choose what she wants to do with the file. https://capacitorjs.com/docs/apis/share
I did not find any other solution to show or download those privately stored files. FileOpener seems to have a lot of problems on Android and does not work either on iOS.
