Deep linking from Web to PWA (Standalone Version)

Question

I have a web app that it can be installed as standalone application in the homescreen thanks to PWA standard.

When a user forget his password, a email is sent to him with a link to reset the password.

Question is:

Can I deep-link to the already-installed standalone version instead of the web application in chrome browser? I'd like to achieve this behaviour:

• User clicks in email link from gmail application.
• OS check if link matches with any url schema pre-registered in the system (This is the step that I don't really know if it's possible from web right now)
• If found, open the standalone version. Otherwise, open the browser.

Thanks in advance!

Cheers

There is an example of describing intent filters in json here. The relevant section of the manifest is intent_filters

{
  "manifest_package": "org.chromium.webapk.test",
  "scope_url": "https://pwa.rocks/",
  "intent_filters": {
    "scope_url_scheme": "https",
    "scope_url_host": "pwa.rocks",
    "scope_url_path": "/"
  },
  "start_url": "https://pwa.rocks/",
  "display_mode": "standalone",
  "orientation": "portrait",
  "theme_color": "2147483648L",
  "background_color": "2147483648L",
  "icon_urls_and_icon_murmur2_hashes": "http://www.pwa.rocks/icon1.png 0 http://www.pwa.rocks/icon2.png 0",
  "web_manifest_url": "https://pwa.rocks/pwa.webmanifest",
  "version_code": "1",
  "version_name": "1.0",
  "bound_webapk": {

  }
}
